1. During an assessment, a male client who has recently started taking Haloperidol is displaying certain symptoms. Which of the following findings should the nurse prioritize in reporting to the provider?
- A. Shuffling gait
- B. Neck spasms
- C. Drowsiness
- D. Impotence
Correct answer: B
Rationale: Neck spasms are indicative of acute dystonia, a serious side effect of Haloperidol that requires urgent intervention. Immediate reporting to the provider is crucial to address this potentially harmful condition and ensure the client's safety. Shuffling gait, drowsiness, and impotence are important to monitor but do not pose the same level of immediate risk as acute dystonia. Acute dystonia can lead to serious complications if not promptly treated, making it the priority in this scenario.
2. A client with schizophrenia is being taught strategies to cope with anticholinergic effects of Fluphenazine. Which of the following should the nurse suggest to the client to minimize anticholinergic effects?
- A. Take the medication in the morning to prevent insomnia.
- B. Chew sugarless gum to moisten the mouth.
- C. Use cooling measures to decrease fever.
- D. Take an antacid to relieve nausea.
Correct answer: B
Rationale: Chewing sugarless gum is an effective strategy to manage dry mouth, a common anticholinergic effect of Fluphenazine. By stimulating saliva production, sugarless gum helps to moisten the mouth and alleviate the discomfort associated with dryness. This intervention can improve the client's oral health and overall comfort while taking the medication. The other options are not directly related to alleviating anticholinergic effects. Taking the medication in the morning to prevent insomnia does not address anticholinergic effects specifically. Using cooling measures to decrease fever is not relevant to managing dry mouth caused by anticholinergic effects. Taking an antacid to relieve nausea is unrelated to managing dry mouth, which is the focus of anticholinergic effects.
3. A patient on a medical-surgical unit administers a hypnotic medication to an older adult client at 2100. The next morning, the client is drowsy and wants to sleep instead of eating breakfast. Which of the following factors should the nurse identify as a possible reason for the client's drowsiness?
- A. Reduced cardiac function
- B. First-pass effect
- C. Reduced hepatic function
- D. Increased gastric motility
Correct answer: C
Rationale: In older adults, reduced hepatic function can lead to prolonged effects of medications metabolized by the liver. This prolonged effect may result in drowsiness the next morning. Adjusting the dosage of the hypnotic medication may be necessary for this client. Choices A, B, and D are incorrect. Reduced cardiac function (Choice A) is not typically associated with drowsiness due to medication effects. The first-pass effect (Choice B) relates to the initial metabolism of a drug in the liver before reaching systemic circulation, which is not directly linked to drowsiness the next morning. Increased gastric motility (Choice D) does not commonly cause drowsiness as described in the scenario.
4. A client in the operating room received a dose of Succinylcholine, leading to muscle rigidity and a sudden rise in body temperature. The nurse should anticipate a prescription for which of the following medications?
- A. Neostigmine
- B. Naloxone
- C. Dantrolene
- D. Vecuronium
Correct answer: C
Rationale: Muscle rigidity and a sudden rise in temperature are indicative of malignant hyperthermia, a potential complication of succinylcholine. Dantrolene is the drug of choice to treat malignant hyperthermia as it acts on skeletal muscles to reduce metabolic activity and counteract the symptoms. Neostigmine (Choice A) is used to reverse the effects of non-depolarizing neuromuscular blocking agents, not for malignant hyperthermia. Naloxone (Choice B) is an opioid antagonist used for opioid overdose. Vecuronium (Choice D) is a non-depolarizing neuromuscular blocking agent and is not the appropriate medication for malignant hyperthermia.
5. When taking Digoxin, low levels of what can cause toxicity?
- A. Potassium
- B. Calcium
- C. Sodium
- D. Magnesium
Correct answer: A
Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.
