Pharmacology for LPN
1. A client with chronic obstructive pulmonary disease (COPD) is prescribed a metered-dose inhaler (MDI) with a spacer. Which instruction should the nurse reinforce to ensure correct use?
- A. Inhale deeply and slowly after activating the MDI.
- B. Hold the breath for 5 seconds after inhaling the medication.
- C. Rinse the mouth immediately after using the MDI.
- D. Exhale fully before placing the mouthpiece in the mouth.
Correct answer: A
Rationale: Inhaling deeply and slowly after activating the MDI is the correct instruction to ensure effective delivery of the medication to the lungs. This technique helps the medication reach the lower airways where it can be most beneficial in managing COPD symptoms. Inhaling too quickly or not deeply enough may result in improper drug delivery and reduce the effectiveness of the treatment. Holding the breath for 5 seconds after inhaling the medication (Choice B) may not be necessary and could cause discomfort without additional benefits. Rinsing the mouth immediately after using the MDI (Choice C) is not necessary unless specified by the healthcare provider. Exhaling fully before placing the mouthpiece in the mouth (Choice D) is not ideal as it may result in inadequate medication delivery to the lungs.
2. When teaching a client about the adverse effects of simvastatin, which of the following findings should be included as an adverse effect?
- A. Tinnitus
- B. Muscle pain
- C. Diarrhea
- D. Facial flushing
Correct answer: B
Rationale: Muscle pain should be included as an adverse effect when teaching a client about simvastatin. It can be a sign of rhabdomyolysis, a severe side effect associated with statins like simvastatin that involves muscle breakdown. Monitoring for muscle pain is crucial to prevent serious complications and ensure timely intervention. Tinnitus, diarrhea, and facial flushing are not typically associated with simvastatin use and are less common adverse effects compared to muscle pain.
3. The LPN/LVN is reinforcing instructions to a client on the use of a metered-dose inhaler. The nurse should recognize that the client is using the inhaler correctly if the client takes which action?
- A. Takes a deep breath and then exhales just before administration
- B. Holds the mouthpiece 1 to 2 inches from the mouth
- C. Inhales the medication and then exhales immediately after administration
- D. Performs 3 short inhalations and then exhales deeply after administration
Correct answer: A
Rationale: When using a metered-dose inhaler, the client should take a deep breath and then exhale just before administration. This technique helps ensure that the medication is inhaled effectively. By exhaling before administration, the client can fully inhale the medication into the lungs, maximizing its therapeutic effects. Choice B is incorrect because holding the mouthpiece 1 to 2 inches from the mouth is not a crucial step for using a metered-dose inhaler correctly. Choice C is incorrect because inhaling the medication and then exhaling immediately after administration would not allow the medication to be adequately absorbed into the lungs. Choice D is incorrect because performing 3 short inhalations and then exhaling deeply after administration is not the correct technique for using a metered-dose inhaler.
4. A client with heart failure is prescribed an angiotensin-converting enzyme (ACE) inhibitor. What instruction should the nurse reinforce to the client?
- A. Take the medication at bedtime.
- B. Report a persistent dry cough.
- C. Increase potassium-rich foods in the diet.
- D. Avoid taking the medication with meals.
Correct answer: B
Rationale: The correct answer is B. A persistent dry cough is a common side effect of ACE inhibitors and should be reported to the healthcare provider. This symptom can indicate a potential issue with the medication that may require adjustment or discontinuation. Choices A, C, and D are incorrect. Taking the medication at bedtime or with meals is not a specific instruction for ACE inhibitors. Increasing potassium-rich foods in the diet is not directly related to ACE inhibitor therapy and may not be suitable for all patients.
5. The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?
- A. Blood glucose
- B. Serum sodium
- C. Serum potassium
- D. Blood urea nitrogen (BUN)
Correct answer: C
Rationale: The correct answer is C: Serum potassium. When a client is receiving furosemide, a loop diuretic, it can lead to potassium loss. Monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias. Blood glucose (Choice A) is not directly impacted by furosemide. Serum sodium (Choice B) may be affected, but monitoring potassium is more critical due to the risk of arrhythmias. Blood urea nitrogen (BUN) (Choice D) is important for assessing kidney function but is not the most crucial value to monitor in a client taking furosemide.
