1. Which electrolyte imbalance is commonly seen in patients receiving furosemide?

• A. Hypokalemia
• B. Hypercalcemia
• C. Hyponatremia
• D. Hyperkalemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. This electrolyte imbalance necessitates close monitoring to prevent complications such as cardiac arrhythmias. Choices B, C, and D are incorrect. Hypercalcemia is not a common side effect of furosemide. Hyponatremia is more commonly associated with other medications like thiazide diuretics. Hyperkalemia is the opposite electrolyte imbalance and is not typically seen with furosemide use.

2. Which lab value is critical for a patient on heparin therapy?

• A. Monitor aPTT
• B. Monitor INR
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial for patients on heparin therapy as it helps determine the clotting ability of the blood. By monitoring aPTT, healthcare providers can adjust the dosage of heparin to maintain therapeutic levels and prevent bleeding complications. Monitoring INR is more commonly associated with warfarin therapy, not heparin. Monitoring platelet count is important for assessing the risk of bleeding or clotting disorders but is not specific to heparin therapy. Monitoring sodium levels is not directly related to assessing the effectiveness or safety of heparin therapy.

3. How should a healthcare provider monitor a patient receiving heparin therapy?

• A. Monitor aPTT
• B. Monitor platelet count
• C. Monitor sodium levels
• D. Monitor calcium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT (activated partial thromboplastin time) when a patient is receiving heparin therapy. aPTT monitoring is essential for assessing the therapeutic effectiveness of heparin, ensuring the patient is within the desired therapeutic range to prevent both clotting and bleeding. Monitoring platelet count (Choice B) is important for assessing for heparin-induced thrombocytopenia but is not the primary monitoring parameter for heparin therapy. Monitoring sodium levels (Choice C) and calcium levels (Choice D) are not directly related to assessing the therapeutic effectiveness or potential side effects of heparin therapy.

4. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. Take a tablet every 5 minutes for pain relief, up to three doses.
• B. Take this medication with a glass of water.
• C. Chew the tablet for faster absorption.
• D. Store the tablets in a refrigerator.

Correct answer: A

Rationale: The correct answer is A: 'Take a tablet every 5 minutes for pain relief, up to three doses.' Nitroglycerin sublingual tablets are used to relieve chest pain or to prevent chest pain before activities known to cause angina. The tablets should be taken every 5 minutes for pain relief, up to three doses, as prescribed. Choice B is incorrect because nitroglycerin sublingual tablets should be placed under the tongue until they dissolve, not taken with water. Choice C is incorrect because nitroglycerin sublingual tablets should not be chewed but placed under the tongue for absorption. Choice D is incorrect because nitroglycerin tablets should be stored in their original container at room temperature away from light and moisture.

5. A nurse is assessing a client who is 2 hours postoperative following a gastrectomy. Which of the following findings should the nurse report to the provider?

• A. Heart rate of 94/min
• B. Oxygen saturation of 88%
• C. Respiratory rate of 18/min
• D. Temperature of 37.6°C (99.7°F)

Correct answer: B

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a serious condition post-gastrectomy. Hypoxemia can lead to inadequate oxygen delivery to tissues, potentially causing complications like organ dysfunction or failure. This finding requires immediate attention to prevent further deterioration. The heart rate, respiratory rate, and temperature are within normal ranges for a client post-gastrectomy, so they do not require immediate reporting to the provider.
