A client has a new prescription for Digoxin. Which of the following instructions should the nurse include?

Correct Answer: B

Rationale: When educating a client about Digoxin, it is crucial to instruct them to monitor their pulse before taking the medication. Digoxin can lead to bradycardia, so monitoring the pulse is essential to ensure it is not below 60 beats per minute before taking each dose. If the pulse is low, the client should hold the dose and seek guidance from their healthcare provider. Choices A, C, and D are incorrect. Taking Digoxin with food may affect its absorption, Digoxin is not known to increase appetite, and feeling nauseated does not necessarily indicate the need to discontinue the medication.

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.

Correct Answer: C

Rationale: The correct answer is C: 'Rinse your mouth after each use.' Beclomethasone can cause oral candidiasis (thrush) as an adverse effect. Rinsing the mouth after each use helps reduce the risk of developing thrush by removing any residue of the medication from the mouth, which can promote fungal growth. Choices A, B, and D are incorrect. Taking the medication with meals, increasing calcium-rich foods intake, or limiting fluid intake are not specific instructions related to minimizing the side effect of oral candidiasis associated with Beclomethasone.

Correct Answer: D

Rationale: The correct instruction for a client prescribed with Cephalexin is to complete the full course of medication. This is crucial to ensure the infection is completely treated and to reduce the risk of antibiotic resistance. Choices A, B, and C are incorrect. Taking Cephalexin with an antacid is generally not recommended as it may reduce its effectiveness. While dairy products can interfere with certain antibiotics, they do not have a direct interaction with Cephalexin. Stools turning black is not an expected side effect of Cephalexin.

Correct Answer: C

Rationale: Digoxin is the correct answer. It is a medication known for its positive inotropic effects, which increase cardiac output, and negative chronotropic effects, which slow the heart rate. These effects are achieved by inhibiting the sodium-potassium ATPase pump in myocardial cells. Therefore, Digoxin is commonly prescribed to manage conditions like heart failure and atrial fibrillation, where enhancing cardiac output and reducing heart rate are beneficial. Choices A, B, and D are incorrect because Heparin is an anticoagulant, Alprazolam is a benzodiazepine used for anxiety disorders, and Levothyroxine is a thyroid hormone replacement drug, none of which have the specified therapeutic effects on cardiac function.

Correct Answer: C

Rationale: The correct answer is C: Decrease or cessation of seizures without excessive sedation. Phenytoin is primarily used as an antiepileptic medication to manage and prevent seizures. It does not directly impact symptoms of PTSD (Choice A), resolution of signs of infection (Choice B), or prevention or relief of bronchospasm (Choice D). Therefore, the desired outcome of Phenytoin is to control seizures effectively while avoiding excessive sedation.

Correct Answer: A

Rationale: The correct answer is A: 'Expect orange-yellow discoloration of urine and skin.' Sulfasalazine can cause this harmless side effect, which does not require discontinuation of the medication. Option B is incorrect because Sulfasalazine is usually taken with food to minimize gastrointestinal side effects. Option C is incorrect as a sore throat is not a common reason to stop the medication. Option D is not directly related to the side effects of Sulfasalazine.

Correct Answer: A

Rationale: A common adverse effect of lisinopril is a persistent dry cough. Lisinopril is an ACE inhibitor that can cause irritation in the respiratory tract, leading to a cough. Monitoring for a persistent cough is essential as it may indicate a serious adverse effect that requires medical attention. Hyperglycemia (Choice B) is not a common adverse effect of lisinopril. Headache (Choice C) and dry mouth (Choice D) are not typically associated with lisinopril use. Therefore, the correct answer is A: Cough.

Correct Answer: A

Rationale: NRTIs inhibit the enzyme reverse transcriptase, essential for HIV replication. By preventing this process, viral replication is hindered, ultimately reducing the viral load in the body. Option A correctly explains the mechanism of action of NRTIs in treating HIV infection. Choices B, C, and D describe mechanisms of action that do not align with how NRTIs work in HIV treatment. B is incorrect because NRTIs do not target protein synthesis within the HIV cell. C is incorrect as NRTIs do not affect the cell wall of the HIV virus. D is incorrect because NRTIs do not block HIV entry into cells.
