1. A patient is receiving IV heparin for a deep-vein thrombosis and 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: Protamine is the antidote for heparin, as it reverses its anticoagulant effects. In cases of heparin overdose or if there is excessive bleeding, administering protamine can quickly neutralize the effects of heparin, helping to prevent further bleeding complications.
2. 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.
3. A client in a coronary care unit is being admitted after CPR post cardiac arrest. The client is receiving IV lidocaine at 2 mg/min. When the client asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?
- A. Prevents dysrhythmias
- B. Slows intestinal motility
- C. Dissolves blood clots
- D. Relieves pain
Correct answer: A
Rationale: Lidocaine is administered to prevent dysrhythmias by delaying conduction in the heart and reducing the automaticity of heart tissue. This action helps stabilize the heart's electrical activity and prevent life-threatening arrhythmias post-cardiac arrest. Choices B, C, and D are incorrect as lidocaine is not used for slowing intestinal motility, dissolving blood clots, or relieving pain in this context.
4. A client has a prescription for Clonidine to treat hypertension. Which of the following instructions should the nurse include?
- A. Discontinue the medication if you experience dry mouth.
- B. Take the medication at the same time each day.
- C. Double the dose if you miss a dose.
- D. Avoid drinking orange juice while taking this medication.
Correct answer: B
Rationale: Correct Answer: Taking Clonidine at the same time each day is crucial to ensure consistent blood levels and effectively manage blood pressure. Consistency in timing helps optimize the medication's effectiveness in controlling hypertension.
5. A healthcare professional is monitoring a client who is receiving spironolactone. Which of the following findings should the professional report to the provider?
- A. Serum Sodium 144 mEq/L
- B. Urine output 120 mL in 4 hours
- C. Serum Potassium 5.2 mEq/L
- D. Blood Pressure 140/90 mm Hg
Correct answer: C
Rationale: A serum potassium level of 5.2 mEq/L indicates hyperkalemia, which is a potentially dangerous condition. Spironolactone, a potassium-sparing diuretic, can cause potassium retention, leading to hyperkalemia. This electrolyte imbalance can result in serious consequences such as cardiac dysrhythmias. The healthcare professional should promptly report this finding to the provider, withhold the medication, and take appropriate actions to prevent complications. Monitoring and managing potassium levels are crucial in clients receiving spironolactone. The other options do not directly relate to the potential adverse effects of spironolactone and are within normal limits, making them less urgent to report.
