LPN Pharmacology Practice Questions
1. The client needs instruction on using a metered-dose inhaler (MDI). Which instruction should be given?
- A. Inhale the medication and then exhale immediately
- B. Exhale fully, then place the inhaler in your mouth and inhale deeply while pressing the canister
- C. Take two short breaths before inhaling the medication
- D. Hold your breath for 5 seconds after inhaling the medication
Correct answer: B
Rationale: The correct technique for using a metered-dose inhaler (MDI) involves exhaling fully before inhaling deeply while pressing the canister to ensure effective delivery of the medication. Choice A is incorrect as exhaling should precede inhaling. Choice C is incorrect as taking two short breaths is not part of the correct technique. Choice D is incorrect as there is no need to hold the breath for a specific time after inhaling the medication.
2. A client with a history of angina pectoris complains of substernal chest pain. The nurse checks the client's blood pressure and administers nitroglycerin 0.4 mg sublingually. Five minutes later, the client is still experiencing chest pain. If the blood pressure is still stable, what should the nurse do next?
- A. Administer another nitroglycerin tablet.
- B. Apply 1 to 3 L/minute of oxygen via nasal cannula.
- C. Call for a 12-lead electrocardiogram (ECG) to be performed.
- D. Wait an additional 5 minutes, then give a second nitroglycerin tablet.
Correct answer: A
Rationale: When a client with angina pectoris continues to experience chest pain despite initial nitroglycerin administration and stable blood pressure, the appropriate next step is to administer another nitroglycerin tablet. This helps to further dilate coronary arteries, improving blood flow to the heart muscle and relieving chest pain. Applying oxygen via nasal cannula (Choice B) may be necessary if the client displays signs of respiratory distress or hypoxemia, but in this case, the priority is addressing the unresolved chest pain. Calling for a 12-lead electrocardiogram (ECG) (Choice C) is important to assess for any changes in the client's cardiac status, but administering another nitroglycerin tablet takes precedence in managing the ongoing chest pain. Waiting an additional 5 minutes before giving a second nitroglycerin tablet (Choice D) may delay symptom relief and potentially worsen the client's condition if the chest pain persists.
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. The client is scheduled to undergo a treadmill stress test. Which instruction should the client be reinforced with?
- A. Eat a light meal before the test.
- B. Wear comfortable shoes and clothing.
- C. Avoid all physical activity the morning of the test.
- D. Take prescribed medications right before the test.
Correct answer: B
Rationale: The correct answer is B: 'Wear comfortable shoes and clothing.' Wearing comfortable shoes and clothing is crucial for the client undergoing a treadmill stress test to ensure they can complete the test without discomfort. The right attire will help the client move freely and reduce the risk of any hindrance during the test, which requires physical activity. Choices A, C, and D are incorrect. A light meal before the test may be recommended, but it's not as crucial as wearing suitable attire. Avoiding physical activity the morning of the test is not necessary as the test requires physical activity. Taking prescribed medications right before the test instructions should be followed as per the healthcare provider's advice and not as a general rule for all clients undergoing the test.
5. A healthcare provider is assisting in the care of a client who is having central venous pressure (CVP) measurements taken. The healthcare provider should assist by placing the bed in which position for the reading?
- A. Flat
- B. Semi-Fowler's
- C. Trendelenburg
- D. Reverse Trendelenburg
Correct answer: A
Rationale: Central venous pressure (CVP) measurements are most accurate when the client is lying flat, as this allows for a consistent baseline. Placing the bed flat ensures that the hydrostatic pressure within the vena cava is not affected by the client's position, providing a more precise reading. Choice B (Semi-Fowler's) elevates the head of the bed at a 30-45 degree angle, which could affect the accuracy of CVP readings. Choices C (Trendelenburg) and D (Reverse Trendelenburg) involve extreme positions that would not be suitable for obtaining accurate CVP measurements.
