1. A client is receiving morphine sulfate subcutaneously for pain. Because morphine sulfate has been prescribed for this client, which nursing action would be included in the plan of care?

A. Encourage fluid intake.
B. Monitor the client's temperature.
C. Maintain the client in a supine position.
D. Encourage the client to cough and deep breathe.

Correct answer: D

Rationale: Morphine sulfate suppresses the cough reflex, which can lead to the retention of secretions in the lungs. Encouraging the client to cough and deep breathe helps prevent pneumonia by clearing the airways of any accumulated secretions. This intervention is crucial in clients receiving morphine sulfate to maintain optimal respiratory function.

2. A client with coronary artery disease complains of substernal chest pain. After checking the client's heart rate and blood pressure, a nurse administers nitroglycerin, 0.4 mg, sublingually. After 5 minutes, the client states, 'My chest still hurts.' Select the appropriate actions that the nurse should take.

A. Call a code blue.
B. Contact the registered nurse.
C. Contact the client's family.
D. Assess the client's pain level.

Correct answer: B

Rationale: The correct action for the nurse to take in this situation is to contact the registered nurse. When a client with coronary artery disease experiences chest pain and does not achieve relief after the initial administration of nitroglycerin, it is crucial to inform the registered nurse promptly. Following the usual guideline for nitroglycerin administration, the nurse may administer a second tablet after assessing the client's pain level. The nurse should continue to assess the client's pain and monitor vital signs before each dose administration. Calling a code blue is not warranted at this point, as the client's condition does not indicate an immediate life-threatening emergency. Contacting the client's family is not necessary unless requested by the client.

3. A client who is receiving digoxin (Lanoxin) daily has a serum potassium level of 3.0 mEq/L and is complaining of anorexia. A healthcare provider prescribes a digoxin level to rule out digoxin toxicity. A nurse checks the results, knowing that which of the following is the therapeutic serum level (range) for digoxin?

A. 3 to 5 ng/mL
B. 0.5 to 2 ng/mL
C. 1.2 to 2.8 ng/mL
D. 3.5 to 5.5 ng/mL

Correct answer: B

Rationale: The therapeutic serum level for digoxin ranges from 0.5 to 2 ng/mL. This range is considered optimal for therapeutic effects while minimizing the risk of toxicity. Levels above 2 ng/mL may lead to digoxin toxicity, which can manifest as anorexia among other symptoms. Therefore, the nurse should be vigilant in monitoring the digoxin levels to ensure the client's safety and therapeutic effectiveness of the medication.

4. Sildenafil (Viagra) is prescribed to treat a client with erectile dysfunction. A nurse reviews the client's medical record and would question the prescription if which of the following is noted in the client's history?

A. Neuralgia
B. Insomnia
C. Use of nitroglycerin
D. Use of multivitamins

Correct answer: C

Rationale: The correct answer is C. Sildenafil (Viagra) enhances the vasodilating effect of nitric oxide and is contraindicated with the concurrent use of organic nitrates and nitroglycerin. Using nitroglycerin together with Viagra can lead to severe hypotension and cardiovascular collapse, making it unsafe to combine both medications.

5. Mycophenolate mofetil (CellCept) is prescribed for a client as prophylaxis for organ rejection following an allogeneic renal transplant. Which of the following instructions does the nurse reinforce regarding administration of this medication?

A. Administer on an empty stomach.
B. Take the medication with a calcium-type antacid.
C. Open the capsule and mix with food for administration.
D. Contact the health care provider (HCP) if a sore throat occurs.

Correct answer: D

Rationale: The correct instruction for administering mycophenolate mofetil (CellCept) is to contact the healthcare provider (HCP) if unusual bleeding or bruising, sore throat, or other adverse effects occur. It is essential not to open or crush the capsules to maintain the medication's efficacy.
