1. A hospitalized client receiving IV heparin for a deep-vein thrombosis begins vomiting blood. After the heparin has been stopped, which of the following medications should the nurse prepare to administer?
- A. Vitamin K1
- B. Atropine
- C. Protamine
- D. Calcium gluconate
Correct answer: C
Rationale: In this scenario, the client is experiencing a serious complication of heparin therapy, likely due to heparin-induced thrombocytopenia. Protamine is the antidote for heparin and can reverse its anticoagulant effects. It is essential to administer protamine promptly to counteract the effects of heparin and manage the bleeding. Vitamin K1 is used to reverse the effects of warfarin, not heparin. Atropine is used to treat bradycardia or some types of poisoning. Calcium gluconate is used to manage hyperkalemia or calcium channel blocker toxicity, not to reverse heparin's effects.
2. A client has a new prescription for Spironolactone. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Hypocalcemia
- D. Hyponatremia
Correct answer: A
Rationale: Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia due to its mechanism of action. Hyperkalemia can cause muscle weakness and cardiac dysrhythmias. Therefore, the nurse should educate the client to monitor for signs and symptoms of hyperkalemia while taking Spironolactone.
3. The nurse is caring for a client who has chronic angina. Treatment for the condition has been unsuccessful. Which medication does the nurse anticipate will be prescribed?
- A. Atenolol (Tenormin)
- B. Nitroglycerin (Nitrostat)
- C. Sildenafil (Viagra)
- D. Ranolazine (Ranexa)
Correct answer: D
Rationale: In cases of chronic angina where initial treatment has not been successful, Ranolazine (Ranexa) is often prescribed. This medication helps by reducing the frequency of angina episodes. Atenolol, Nitroglycerin, and Sildenafil are also used in angina management but Ranolazine is more specifically indicated in cases of refractory angina where other treatments have failed.
4. A client has a new prescription for Ferrous sulfate. Which of the following instructions should be included?
- A. Take this medication with milk.
- B. Take this medication on an empty stomach.
- C. Take this medication before bedtime.
- D. Take this medication with antacids.
Correct answer: B
Rationale: The correct answer is B: 'Take this medication on an empty stomach.' Ferrous sulfate is best absorbed on an empty stomach. Instruct the client to take it 1 hour before or 2 hours after meals to maximize absorption and avoid interactions with food or beverages that may decrease absorption. Choice A is incorrect because taking Ferrous sulfate with milk can decrease its absorption. Choice C is incorrect as there is no specific benefit to taking it before bedtime. Choice D is incorrect as antacids can interfere with the absorption of Ferrous sulfate.
5. A client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the nurse?
- A. Perform immediate gastric lavage.
- B. Prepare the client for hemodialysis.
- C. Administer an additional oral dose of lithium.
- D. Request a stat repeat of the laboratory test.
Correct answer: A
Rationale: In a client with a plasma lithium level of 2.1 mEq/L, immediate gastric lavage is appropriate for severe toxicity. Gastric lavage can help lower the client's lithium level by removing the unabsorbed lithium from the stomach.
