Nursing Elites

1. A client has a new prescription for Digoxin. Which of the following findings should the nurse identify as a potential sign of Digoxin toxicity?

• A. Nausea
• B. Dry mouth
• C. Hypoglycemia
• D. Tinnitus

Correct answer: A

Rationale: Nausea is a potential sign of Digoxin toxicity. Other signs of Digoxin toxicity include vomiting, visual disturbances, and confusion. Nausea can be an early indicator of toxicity and should be closely monitored by the nurse. Dry mouth and hypoglycemia are not typically associated with Digoxin toxicity. Tinnitus is more commonly associated with medications like aspirin or loop diuretics, not Digoxin.

2. A client is receiving IV Dopamine for the treatment of shock. Which of the following findings indicates that the medication is effective?

• A. Increased heart rate
• B. Decreased blood pressure
• C. Increased urine output
• D. Decreased respiratory rate

Correct answer: C

Rationale: The correct answer is increased urine output. Dopamine increases cardiac output and improves renal perfusion, leading to increased urine output. This response indicates that the medication is effective in treating shock by enhancing renal function and perfusion. Choices A, B, and D are incorrect because an increased heart rate, decreased blood pressure, and decreased respiratory rate are not findings that indicate the effectiveness of IV Dopamine in treating shock.

3. In reviewing a client's health record, which condition would be a contraindication for using Propranolol to treat hypertension?

• A. Asthma
• B. Glaucoma
• C. Hypertension
• D. Tachycardia

Correct answer: A

Rationale: Propranolol is a nonselective beta-adrenergic blocker that blocks both beta1 and beta2 receptors. Blocking beta2 receptors in the lungs can lead to bronchoconstriction, making it unsuitable for clients with asthma. Therefore, asthma is a contraindication for taking Propranolol. Glaucoma, hypertension, and tachycardia are not contraindications for using Propranolol to treat hypertension.

4. Which drug class has been found to decrease mortality if given within 8 hours of an MI due to a decrease in cardiac workload?

• A. Antiplatelets
• B. Beta-adrenergic blockers
• C. ACE inhibitors
• D. Calcium channel blockers

Correct answer: B

Rationale: Beta-adrenergic blockers have been shown to decrease mortality when administered within 8 hours of a myocardial infarction (MI). They do so by reducing cardiac workload, which helps improve outcomes post-MI. These drugs work by blocking the effects of adrenaline on the heart, leading to decreased heart rate, blood pressure, and myocardial oxygen demand, thereby protecting the heart muscle from further damage. This makes them a crucial part of the treatment regimen for acute coronary syndromes like MI.

5. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?

• A. These medications work by blocking HIV entry into cells.
• B. These medications work by weakening the cell wall of the HIV virus.
• C. These medications work by inhibiting enzymes to prevent HIV replication.
• D. These medications work by preventing protein synthesis within the HIV cell.

Correct answer: C

Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.
