1. A healthcare professional is preparing to administer morphine 4 mg IV to a client. Available is morphine 10 mg/mL. How many mL should the healthcare professional administer?

• A. 0.2 mL
• B. 0.4 mL
• C. 0.6 mL
• D. 0.8 mL

Correct answer: B

Rationale: To administer 4 mg from a solution of 10 mg/mL, the healthcare professional should administer 0.4 mL. The calculation is done by dividing the desired dose (4 mg) by the concentration of the solution (10 mg/mL), which equals 0.4 mL. Choice A (0.2 mL) is incorrect because it is half of the correct calculation. Choice C (0.6 mL) is incorrect because it is 50% more than the correct calculation. Choice D (0.8 mL) is incorrect because it exceeds the correct calculation.

2. A healthcare professional is about to administer Propranolol to a patient. The healthcare professional takes the patient's apical pulse and documents it as 58 bpm. How should the healthcare professional proceed?

• A. Administer the medication as prescribed
• B. Administer half of the normal dose
• C. Consider the extended-release form of the medication
• D. Withhold administration of the medication and notify the healthcare provider

Correct answer: D

Rationale: When a patient's apical pulse is 58 bpm, it is below the normal range. Propranolol is a beta-blocker that can further lower the heart rate. Therefore, it is crucial to withhold the medication and notify the healthcare provider to evaluate the patient's condition. Administering Propranolol in this situation can exacerbate bradycardia, leading to serious complications. Choosing to administer the medication as prescribed (Choice A) can put the patient at risk. Administering half of the normal dose (Choice B) without healthcare provider guidance is not appropriate in this case. Considering the extended-release form of the medication (Choice C) does not address the immediate concern of bradycardia and is not the best course of action.

3. A client receiving chemotherapy with Methotrexate asks why Leucovorin is being given. Which of the following responses should the nurse use?

• A. Leucovorin reduces the risk of a transfusion reaction from Methotrexate.
• B. Leucovorin increases platelet production and prevents bleeding.
• C. Leucovorin potentiates the cytotoxic effects of Methotrexate.
• D. Leucovorin protects healthy cells from Methotrexate's toxic effects.

Correct answer: D

Rationale: Leucovorin, a folic acid derivative and an antagonist to Methotrexate, is given within 12 hours of high doses of Methotrexate to protect healthy cells from the toxic effects of Methotrexate. It helps to reduce the bone marrow suppression and gastrointestinal side effects caused by Methotrexate, supporting the client's overall well-being during chemotherapy treatment. Choices A, B, and C are incorrect because Leucovorin does not reduce the risk of a transfusion reaction from Methotrexate, increase platelet production, prevent bleeding, or potentiate the cytotoxic effects of Methotrexate. Instead, Leucovorin works by rescuing healthy cells from the toxic effects of Methotrexate.

4. A client has a new prescription for Aspirin for the prevention of myocardial infarction. Which of the following findings should be identified as an adverse effect?

• A. Nausea
• B. Bruising
• C. Dizziness
• D. Dry mouth

Correct answer: B

Rationale: Bruising is an adverse effect to be monitored when a client is prescribed Aspirin for the prevention of myocardial infarction due to its association with increased bleeding risk. Aspirin's antiplatelet effect can lead to bruising and other signs of bleeding, necessitating close observation to prevent complications. Nausea, dizziness, and dry mouth are not typically recognized adverse effects of Aspirin therapy for myocardial infarction prevention.

5. A healthcare professional is caring for a client who has a new prescription for Lisinopril. Which of the following laboratory values should the professional monitor?

• A. Serum potassium
• B. Serum sodium
• C. Serum calcium
• D. Serum magnesium

Correct answer: A

Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing the excretion of potassium in the kidneys. Monitoring serum potassium levels is essential to prevent complications such as cardiac arrhythmias. Therefore, the healthcare professional should closely monitor the client's serum potassium levels when they are on Lisinopril. Choices B, C, and D are incorrect because Lisinopril primarily affects potassium levels due to its mechanism of action as an ACE inhibitor. Serum sodium, calcium, and magnesium levels are not typically affected by Lisinopril in the same way as potassium.
