1. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and is experiencing muscle weakness. The nurse should anticipate a prescription for which of the following medications?
- A. Neostigmine
- B. Naloxone
- C. Dantrolene
- D. Vecuronium
Correct answer: A
Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers by increasing acetylcholine levels at the neuromuscular junction, thereby helping to restore muscle strength. Naloxone is an opioid antagonist used to reverse opioid effects, not neuromuscular blockade. Dantrolene is a skeletal muscle relaxant used to treat malignant hyperthermia or neuroleptic malignant syndrome, not to reverse neuromuscular blockade. Vecuronium is a nondepolarizing neuromuscular blocking agent, like the one the client received, and is not used to reverse its effects.
2. A client has a prescription for furosemide. Which of the following instructions should the nurse include?
- A. Take furosemide in the morning.
- B. Eat a diet high in potassium.
- C. Avoid foods high in magnesium.
- D. Limit fluid intake to 1 liter per day.
Correct answer: B
Rationale: The correct instruction for a client taking furosemide is to eat a diet high in potassium. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Consuming foods rich in potassium can help maintain normal potassium levels in the body and counteract the potential side effect of furosemide. Choices A, C, and D are incorrect because taking furosemide in the morning does not specifically relate to its effectiveness or side effects, avoiding foods high in magnesium is not a primary concern when taking furosemide, and limiting fluid intake to 1 liter per day is not a general recommendation for individuals taking furosemide.
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. In which patient could the drug Senna potentially be indicated?
- A. A patient with an eating disorder
- B. A patient who has not passed stool in 5 days
- C. A patient with anal fissures
- D. A patient with a history of hemorrhoids
Correct answer: B
Rationale: Senna is a stimulant laxative commonly used to treat constipation by stimulating bowel movements. It is typically indicated for patients who have not passed stool in several days, thereby helping to relieve constipation. Patients with eating disorders may require different treatments related to their condition. Patients with anal fissures or a history of hemorrhoids may need treatments targeted at those specific issues, which may not involve Senna.
5. A client has a new prescription for Furosemide. Which of the following instructions should be included?
- A. Take this medication at bedtime.
- B. Avoid eating foods high in potassium.
- C. Change positions slowly.
- D. Take this medication with meals.
Correct answer: C
Rationale: Furosemide is a diuretic that can lead to orthostatic hypotension, causing dizziness and falls. Instructing the client to change positions slowly helps prevent these adverse effects by allowing the body to adjust to postural changes gradually, reducing the risk of significant blood pressure drops upon standing up quickly.
