1. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and has 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, such as the one the client received. It works by inhibiting the breakdown of acetylcholine, thereby enhancing neuromuscular transmission and reversing muscle weakness caused by the neuromuscular blocking agent.
2. A client is prescribed Bethanechol to treat urinary retention. Which of the following findings is a manifestation of muscarinic stimulation?
- A. Dry mouth
- B. Hypertension
- C. Excessive perspiration
- D. Fecal impaction
Correct answer: C
Rationale: Bethanechol is a muscarinic agonist, which stimulates muscarinic receptors. Activation of these receptors can lead to increased sweating (excessive perspiration) as a manifestation of muscarinic stimulation. Options A, B, and D are not typically associated with muscarinic stimulation. Dry mouth is a common side effect of anticholinergic medications, hypertension is not a common manifestation of muscarinic stimulation, and fecal impaction is not directly related to muscarinic receptor activation.
3. Which of the following drugs is associated with hepatitis as a reaction?
- A. Valproic acid
- B. Quinidine
- C. Isoniazid
- D. Ethosuximide
Correct answer: C
Rationale: Hepatitis is a known side effect of isoniazid. It is important to monitor patients on isoniazid for signs of liver damage, including hepatitis, as part of their treatment regimen for tuberculosis.
4. A school-age child has a new prescription for Atomoxetine. The nurse should monitor the client for which of the following adverse effects of this medication?
- A. Kidney toxicity
- B. Liver damage
- C. Seizure activity
- D. Adrenal insufficiency
Correct answer: B
Rationale: Liver damage is an adverse effect of Atomoxetine. The nurse should monitor for manifestations such as jaundice, upper abdominal tenderness, darkening of urine, and elevated liver enzymes. It is crucial to be vigilant for signs of liver damage to ensure early detection and intervention to prevent further complications. Kidney toxicity is not a common adverse effect of Atomoxetine. Seizure activity and adrenal insufficiency are also not typically associated with this medication.
5. To which pharmacologic classification does the drug propranolol belong?
- A. Beta Blockers
- B. Cholinergics
- C. Immune globulins
- D. Barbiturates
Correct answer: A
Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.
