Nursing Elites

1. A patient is prescribed acetaminophen 650 mg PO every 6 hr PRN for pain. The available acetaminophen liquid is 500 mg/5 mL. How many mL should the nurse administer per dose?

• A. 6.5 mL
• B. 7 mL
• C. 5 mL
• D. 8 mL

Correct answer: A

Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the nurse should administer 6.5 mL of acetaminophen liquid per dose to provide the prescribed 650 mg of acetaminophen. Choice B, 7 mL, is incorrect because the correct calculation results in 6.5 mL. Choice C, 5 mL, is incorrect as it is the concentration of the acetaminophen liquid, not the final volume needed. Choice D, 8 mL, is incorrect because it does not reflect the accurate calculation based on the prescription and concentration.

2. A healthcare professional is reviewing laboratory results for a client who is receiving heparin via continuous IV infusion. Which of the following results indicates that the heparin infusion should be increased?

• A. aPTT of 90 seconds
• B. Platelet count of 150,000/mm³
• C. INR of 1.0
• D. Hgb of 15 g/dL

Correct answer: A

Rationale: An aPTT of 90 seconds is above the therapeutic range for heparin, which typically falls between 60-80 seconds. This indicates that the current heparin dose is too high, and the infusion rate should be decreased to avoid excessive anticoagulation and the risk of bleeding. Monitoring aPTT is crucial in adjusting heparin therapy to maintain it within the therapeutic range.

3. A client is receiving Enoxaparin for the prevention of deep vein thrombosis. Which of the following actions should the nurse take?

• A. Massage the injection site after administration.
• B. Administer the medication intramuscularly.
• C. Administer the medication into the subcutaneous tissue.
• D. Administer the medication into the deltoid muscle.

Correct answer: C

Rationale: Enoxaparin, a medication used for preventing deep vein thrombosis, should be administered into the subcutaneous tissue, typically in the abdomen. Administering the medication intramuscularly (Choice B) or into the deltoid muscle (Choice D) is incorrect because Enoxaparin is specifically formulated for subcutaneous administration. Massaging the injection site after administration (Choice A) is contraindicated as it may lead to tissue damage and affect the absorption of the medication. Therefore, the correct action is to administer the medication into the subcutaneous tissue as directed.

4. How do ACE inhibitors work?

• A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
• B. Block stimulation of beta 1 and beta 2 at the receptor sites
• C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
• D. None of the above

Correct answer: C

Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.

5. A client is prescribed Atorvastatin. Which of the following laboratory values should be monitored to assess for potential adverse effects?

• A. Blood glucose
• B. Creatine kinase
• C. Hemoglobin
• D. Sodium

Correct answer: B

Rationale: Creatine kinase should be monitored in clients taking Atorvastatin as it can indicate muscle damage, a serious adverse effect of statins. Elevated creatine kinase levels may suggest myopathy or rhabdomyolysis, which are potential complications of statin therapy.
