Mastering the art of hands-off, “boundary-aware” problem-solving at the point of care, where your expertise is most visible and valuable.
SECTION 30.3
Bedside Troubleshooting
Applying your knowledge as a hands-on consultant, not a hands-on practitioner.
30.3.1 From Remote Expert to Bedside Consultant: A Shift in Practice
You have spent your entire career becoming a medication expert. But in the hospital, there will be times when your expertise is needed not just in the EHR or over the phone, but in person, at the patient’s bedside. This is one of the most visible and high-value services a pharmacist can provide. A nurse may call you to the floor for a variety of reasons: an IV pump is beeping with an unfamiliar alarm, a parenteral nutrition bag looks cloudy, or a complex multi-line infusion setup needs a second pair of expert eyes. These are moments of truth where you can either solve the problem and become an invaluable resource, or defer and diminish the perceived value of your role.
However, stepping into the patient’s room requires a profound understanding of a new and critical skill: “boundary-aware” consultation. You are a guest in the nursing workspace and the patient’s personal space. You are not there to perform nursing functions. You will not touch the patient, you will not press buttons on the IV pump, and you will not administer medications. Your role is that of a specialized consultant, a medication detective using your eyes, your brain, and your collaborative communication skills to help the nurse solve a problem that falls within your area of expertise. You are there to assess, advise, and confirm.
The Golden Rule of Bedside Troubleshooting: Hands in Pockets
Adopt a literal and figurative “hands in pockets” posture when you are at the bedside. Your value is in your knowledge, not your dexterity. You are there to empower the nurse with your expertise, not to do their job for them. By physically refraining from manipulating equipment, you maintain a clear professional boundary, show respect for the nursing scope of practice, and protect yourself from liability. Your tools are your eyes, your questions, and your ability to explain complex concepts simply. Point, suggest, and confirm—but let the nurse drive.
Masterclass Table: Defining Professional Boundaries at the Bedside
| The Task | The Nurse’s Role (The “Doer”) | The Pharmacist’s Role (The “Advisor”) | Collaborative Communication Script |
|---|---|---|---|
| Programming an IV Pump | Physically enters the rate, dose, and volume into the pump. Scans the patient and the medication. Presses the “Start” button. | Reviews the verified order in the EHR. Reads the pump screen over the nurse’s shoulder to confirm the programmed settings match the verified order. Confirms that the correct drug library entry was selected. | Pharmacist: “Okay, I see the order is for heparin at 18 units per kilo per hour. Can you show me the pump screen? … Perfect, I can confirm the pump is also programmed for 18 units per kilo per hour and you’re in the right guardrail set. Looks great.” |
| Priming IV Tubing or Changing a Bag | Physically spikes the bag, primes the tubing to remove air, hangs the bag on the pole, and connects it to the patient’s IV line. | Confirms the medication bag label is correct (right patient, right drug, right concentration). Confirms the correct type of tubing is being used (e.g., filtered tubing for TPN, protected tubing for light-sensitive drugs). | Pharmacist: “Before you prime that, can I just double-check the bag with you? … Okay, I see it’s for Jane Doe, it’s our standard potassium drip. And that looks like the right smart pump tubing. Everything checks out on my end.” |
| Troubleshooting a Pump Alarm | Responds to the alarm. Physically checks the line for kinks, assesses the IV site, and silences/restarts the pump. | Interprets the alarm message. Visually traces the line from bag to patient to look for obvious problems. Asks guiding questions to help the nurse diagnose the root cause. Provides drug-specific information (e.g., “This drug is known to precipitate at this concentration, let’s check the filter”). | Pharmacist: “I see the pump is alarming for a downstream occlusion. I’m just visually tracing the line down from the pump… it looks like the tubing might be kinked under the bed rail right there. Could you check that spot for me?” |
| Assessing a Patient’s IV Site | Physically touches the patient’s arm, palpates the area for swelling or coolness, and assesses for pain or redness. Makes the clinical judgment to remove or replace the IV. | From a respectful distance, visually inspects the site. Advises the nurse on the potential for the specific drug to be a vesicant or irritant and provides recommendations for extravasation management if needed. | Pharmacist: “I know you’re assessing the site, but from here I can see some significant swelling around that peripheral IV. Since the patient is on IV vancomycin, a known vesicant, we should be concerned about extravasation. I recommend stopping the infusion immediately. I will look up the specific antidote and management protocol for you right now.” |
30.3.2 Troubleshooting the IV Infusion: A “Follow the Flow” Masterclass
When a nurse calls you to the bedside for an IV infusion problem, your approach should be that of a systematic, methodical diagnostician. You will use a mental model called “Follow the Flow,” starting your visual inspection at the source (the IV bag) and logically tracing the path the medication takes all the way to the patient’s vein. This ensures you don’t miss any steps and allows you to rapidly identify the most likely failure points.
Step 1: The Source (The IV Bag)
Your first check is the bag itself. Is the foundation of the infusion correct?
- The “Five Rights” Check: This is second nature to you. Visually confirm with the nurse: Right Patient, Right Drug, Right Dose (Concentration), Right Route (IV), Right Time. Read the label out loud. “Okay, I see the label is for John Smith, it’s Levaquin 750mg in 150mL, which matches the order I see in the chart.”
- Visual Inspection for Particulates/Precipitation: Look at the bag against a light source. Is the solution clear? Do you see any white specks, cloudiness, or crystallization? This is especially critical for drugs known for stability issues, like phenytoin, amiodarone, or calcium/phosphate in TPNs.
- Expiration Dating: Quickly check the Beyond Use Date (BUD) prepared by the pharmacy. Is it still in date?
Step 2: The Path (The Tubing and Filter)
The path from the bag to the pump is a common source of problems that are often easy to spot.
- Line Tracing: This is the most important bedside skill. If a patient has multiple IV lines (a “spaghetti” of tubing), you must visually and carefully trace the specific tubing from the medication bag you just inspected all the way to the channel on the IV pump it’s programmed for, and then all the way to the specific port on the patient’s IV catheter. This single action prevents countless wrong-line errors.
- Check for Kinks and Obstructions: As you trace the line, look for obvious physical blockages. Is the tubing caught in the bed rail? Is the patient lying on it? Is a roller clamp closed?
- Confirm Correct Tubing Type: Your drug expertise is key here. Does this medication require special tubing?
- Filters: “I see you’re hanging TPN. Can we just confirm this tubing has a 1.2 micron filter on it?”
- Light Protection: “This is an IV micafungin bag. Just want to double-check that we are using a light-protective (amber) cover or tubing.”
- Nitroglycerin Tubing: “For this nitroglycerin drip, we need to be using the special low-sorbing tubing to ensure the patient gets the full dose.”
Step 3: The Engine (The Smart Pump)
The IV pump is the heart of the infusion, and its alarms are a frequent reason you’ll be called. Your role is to be the expert interpreter of the pump’s messages and its programming.
You are the Co-Pilot, Not the Pilot
It bears repeating: you do not touch the pump. The nurse is the licensed operator of this device. Your job is to be their “co-pilot,” reading the instruments, cross-checking the flight plan (the order), and offering expert advice, but the nurse has their hands on the controls. Use phrases like “Can you show me the screen?” and “Could you try pressing the ‘channel select’ button?” to guide them.
Masterclass Table: Common Smart Pump Alarms & The Pharmacist’s Playbook
| The Alarm Message | What It Means | Your Diagnostic “Follow the Flow” Investigation | Collaborative Script for the Nurse |
|---|---|---|---|
| “Occlusion Downstream” | The pump is meeting resistance trying to push fluid *after* the pump mechanism. There is a blockage somewhere between the pump and the patient’s vein. |
|
“That alarm means there’s a block somewhere between the pump and the patient. I’m looking at the line, and it seems okay until it gets to the patient’s arm. The IV site looks quite swollen from here. I’m concerned it might be infiltrated. I’d recommend you pause the infusion and assess the site for patency.” |
| “Occlusion Upstream” | The pump is having trouble pulling fluid *before* the pump mechanism. There is a blockage somewhere between the IV bag and the pump. |
|
“That alarm usually means something is blocked above the pump. Could you double-check for me that the roller clamp up by the bag is all the way open?” |
| “Air in Line” | The pump’s sensor has detected one or more air bubbles in the IV tubing. |
|
“The pump is detecting air in the line. I can see a few bubbles in the tubing right below the pump cassette. The IV bag looks like it’s almost empty, that’s likely the cause. You’ll probably need to prime the air out of the line after you hang the new bag.” |
| “Guardrail Alert” or “Library Mismatch” | The nurse has tried to program a dose or rate that is outside the pre-set safety limits (the “guardrails”) in the pump’s drug library, or they haven’t used the library at all. |
|
“Thank you for calling me for this guardrail alert, that’s exactly what it’s there for. I see the order is for 1250 units/hour. Can you show me what you’ve programmed? … Ah, it looks like there was a typo and 12,500 was entered. That’s a great catch by the smart pump. If you reprogram for 1250, it should be within the safety limits.” |
30.3.3 Retail Pharmacist Analogy: Coaching the Confused Patient at the Counter
A Deep Dive into the Analogy
The skill of “boundary-aware” bedside consultation may feel new and intimidating, but you have been practicing the core principles for your entire career at the pharmacy counter. The most direct parallel is when you are teaching a new, anxious diabetic patient how to use their first blood glucose meter.
The Scenario:
You’ve just sold a glucose meter to an elderly patient, Mr. Jones. He opens the box right at the counter and looks completely overwhelmed. He says, “I’m sorry, dear, the nurse showed me in the office, but I’m all thumbs. Can you help me?”
Your “Hands-in-Pockets” Coaching in Action:
What do you do? You don’t grab his finger and perform the blood stick for him. That would be overstepping your bounds, and more importantly, it wouldn’t teach him how to do it himself tomorrow. Instead, you enter a “boundary-aware” coaching mode:
- You Assess and Advise: “Of course, let’s walk through it together. Let’s start with the lancing device. See that dial with the numbers? That’s for the depth. Since it’s your first time, let’s set it to a lower number, like 2.” (You are advising on the “pump settings”).
- You Guide, They Do: “Great. Now, go ahead and put a test strip into the meter… perfect. See how it turned on by itself? Now you’re ready to get a blood sample.” (You are guiding the nurse’s actions).
- You Troubleshoot Alarms: Mr. Jones pokes his finger but doesn’t get a big enough drop of blood. The meter beeps and gives an “Error 2” message. You don’t take the meter from him. You interpret the error. “No problem at all! That error just means the test strip didn’t get enough blood. Let’s try again, and this time, try gently squeezing your finger from the base up to get a better drop.” (You are interpreting the “pump alarm” and providing a solution).
- You Confirm Success: He gets it right the second time. The meter reads 145. “Excellent! You did it perfectly. And 145 is a great number. See? You’ve got this.” (You are confirming the “infusion” is running correctly).
Throughout this entire interaction, you never performed the task for the patient. You used your expert knowledge to empower them to perform the task correctly and safely themselves. This is the exact same mindset and skillset you will bring to the hospital bedside. You are the expert coach, standing alongside the nurse, guiding them to a successful outcome.
