Question 1 of 3

Questioning an unsafe route

An adult has a serum potassium of 3.1 mEq/L and no acute symptoms. The nurse reviews a new order for potassium chloride concentrate, 20 mEq by direct IV push. No potassium has been administered. Which action should the nurse take?

1. Questioning an unsafe route

An adult has a serum potassium of 3.1 mEq/L and no acute symptoms. The nurse reviews a new order for potassium chloride concentrate, 20 mEq by direct IV push. No potassium has been administered. Which action should the nurse take?

Best answer: B

  • A. Administer the concentrate slowly by IV push through a patent line. A patent line and slower pushing do not make this route safe. Concentrated potassium must not be given by direct IV push.
  • B. Do not administer the IV push; contact the prescriber and pharmacist to clarify a safe replacement order. Withhold this unsafe administration and clarify the order. IV replacement requires an appropriately diluted infusion with a prescribed rate and monitoring suited to the client and local protocol.
  • C. Dilute the concentrate in a small syringe and give it by IV push. Diluting in a syringe does not authorize IV push administration. The formulation, dilution, route and rate must all be appropriate.
  • D. Change the order to an oral dose and administer it without contacting the prescriber. The nurse cannot independently change the prescribed route or dose. Clarify an appropriate replacement plan rather than improvise one.

Decisive cue: The order specifies potassium concentrate by direct IV push; none has been administered.

A low potassium result does not make an unsafe administration route acceptable. Verify the complete replacement order.

2. Assessing before the next dose

An adult takes scheduled oral metoprolol tartrate for hypertension. Before the next dose, the nurse confirms a pulse of 44/min and blood pressure of 86/50 mm Hg. The client is awake and reports new dizziness. Which action is most appropriate now?

Best answer: C

  • A. Give the scheduled dose because the medication is taken every day. A familiar schedule does not override new concerning findings. Another dose could worsen bradycardia and hypotension.
  • B. Give half of the prescribed dose without obtaining a new order. An unprescribed half-dose is not a safe substitute for urgent assessment of these findings.
  • C. Do not give the dose now; stay with the client, obtain urgent clinical assessment and support monitoring under the local emergency protocol. Marked bradycardia, hypotension and new dizziness require urgent assessment and support. Do not administer the dose now; escalate and monitor according to the local emergency protocol.
  • D. Give the dose and recheck the pulse and blood pressure in one hour. Giving the dose and waiting an hour delays assessment while potentially worsening the current problem.

Decisive cue: Pulse 44/min, blood pressure 86/50 mm Hg and new dizziness occur together.

Respond to the whole clinical picture. This is not a universal numerical hold rule or advice to stop chronic beta-blocker therapy independently.

3. Checking the exact formulation

An adult receiving prescribed OXYCONTIN (oxycodone extended-release tablets) reports difficulty swallowing this large tablet. The client is alert, breathing normally and has not taken the dose. Which response is safest?

Best answer: A

  • A. Do not alter or administer the tablet; assess the swallowing difficulty and contact the prescriber and pharmacist for an appropriate alternative plan. Preserve the formulation and assess the difficulty before administration. The prescriber and pharmacist can arrange a suitable alternative that addresses swallowing and pain control.
  • B. Crush the tablet and mix it with soft food. Crushing OXYCONTIN disrupts extended release and can expose the client to a potentially fatal dose. Mixing with food does not remove that risk.
  • C. Dissolve the tablet in water before administration. Dissolving this tablet also disrupts its extended-release delivery. It is not an acceptable workaround for swallowing difficulty.
  • D. Substitute an immediate-release oxycodone product using the same schedule without a new order. Immediate-release and extended-release products are not interchangeable on an unchanged schedule without an appropriate prescription.

Decisive cue: The exact product is OXYCONTIN, an extended-release tablet, and swallowing this tablet is difficult.

Check the exact product before altering a medicine. Do not generalize one tablet's instructions to every formulation.

What these three questions teach

1. A valid indication does not make every route safe

The potassium question asks you to notice the administration route before giving any medication. Potassium chloride concentrate must be diluted for an appropriate infusion; direct injection can cause fatal cardiac harm. A slower push or a syringe dilution does not resolve an unsafe IV-push order. Clarify the complete order instead of inventing a different route, dose or rate.

The potassium chloride prescribing information supports this distinction. The example does not prescribe a replacement regimen; actual replacement depends on the client, prescription and local protocol.

2. A routine schedule does not override new findings

In the metoprolol question, the slow pulse, low blood pressure and new dizziness belong together. The decision is to withhold the dose now and seek urgent assessment and monitoring, rather than give it and wait. The AHA adult bradycardia algorithm calls for assessment and support when bradycardia is accompanied by cardiopulmonary compromise, including hypotension. Reducing the dose independently is not a substitute for responding to the findings.

The metoprolol tartrate label lists severe bradycardia as a contraindication. This scenario is not a universal numerical hold rule. It also does not instruct a client to stop long-term beta-blocker treatment independently; the label warns about abrupt cessation of chronic therapy.

3. The exact dosage form matters

The third question specifies OXYCONTIN extended-release tablets. Crushing or dissolving that product can defeat its controlled release. Swallowing difficulty calls for assessment and an appropriate alternative plan, not an improvised change to the tablet or a substitution on the same schedule.

The OXYCONTIN label explains the formulation risk and discusses alternatives for swallowing difficulty. Check the exact product's instructions; do not extend one tablet's directions to every medicine or formulation.

Review the decision, not just the letter

After each question, write three lines:

  • The cue I noticed or missed: a route, a current finding or a formulation.
  • Why my tempting option was weaker: what risk or delay it left unresolved.
  • What I must verify next: the complete order, the client's condition or product-specific instructions.
