Nursing Elites

1. Which of the following drugs is associated with extreme photosensitivity as a reaction?

• A. Digitalis
• B. Niacin
• C. Tetracycline
• D. Fluoroquinolones

Correct answer: C

Rationale: Tetracycline is known to cause extreme photosensitivity reactions, making individuals more sensitive to sunlight and increasing the risk of severe sunburn. It is essential for patients taking tetracycline to protect themselves from excessive sun exposure to prevent adverse reactions.

2. A client is starting therapy with docetaxel. Which of the following findings should the nurse instruct the client to report?

• A. Flushing
• B. Dyspnea
• C. Hyperglycemia
• D. Tinnitus

Correct answer: B

Rationale: The correct answer is B: Dyspnea. The nurse should instruct the client to report dyspnea because it can indicate pulmonary toxicity, a severe adverse effect of docetaxel. Dyspnea may suggest a potential serious condition that needs prompt evaluation and intervention to prevent complications. Flushing (choice A) is more commonly associated with other medications or conditions and is not a common side effect of docetaxel. Hyperglycemia (choice C) and tinnitus (choice D) are also not typically associated with docetaxel therapy and are not priority findings that the nurse should instruct the client to report.

3. When taking Digoxin, low levels of what can cause toxicity?

• A. Potassium
• B. Calcium
• C. Sodium
• D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

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

• A. Take the medication in the morning.
• B. Increase your intake of potassium-rich foods.
• C. Expect your urine to turn orange.
• D. Avoid prolonged sunlight exposure.

Correct answer: B

Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Furosemide is a loop diuretic that can lead to hypokalemia (low potassium levels) due to increased excretion of potassium in the urine. To counteract this effect and maintain electrolyte balance, the client should be advised to increase their intake of potassium-rich foods. This instruction helps prevent potential complications associated with low potassium levels. Choices A, C, and D are incorrect. Taking Furosemide in the morning does not affect its effectiveness; urine turning orange is not an expected side effect of Furosemide; and avoiding prolonged sunlight exposure is not directly related to Furosemide use.

5. A client is receiving heparin therapy. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?

• A. PT
• B. aPTT
• C. INR
• D. Platelet count

Correct answer: B

Rationale: The corrected answer is B: aPTT. The activated partial thromboplastin time (aPTT) is the laboratory value used to monitor the effectiveness of heparin therapy. The aPTT should be maintained at 1.5 to 2 times the normal level to ensure therapeutic anticoagulation. Monitoring aPTT helps healthcare providers adjust heparin doses to achieve the desired anticoagulant effects and prevent complications such as bleeding or clotting. Choice A, PT (prothrombin time), is used to monitor warfarin therapy, not heparin. Choice C, INR (international normalized ratio), is also used to monitor warfarin therapy. Choice D, platelet count, is important for assessing the risk of bleeding, but it does not directly monitor the effectiveness of heparin therapy.
