1. When caring for a client prescribed Digoxin, which of the following laboratory values should the nurse monitor to assess for potential toxicity?
- A. Sodium
- B. Potassium
- C. Magnesium
- D. Calcium
Correct answer: B
Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin. Sodium, magnesium, and calcium levels are not directly associated with Digoxin toxicity; hence, they are not the primary focus for monitoring in this case.
2. 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.
3. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?
- A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
- C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
- D. Draw a peak level at 0900 and a trough level at 2100.
Correct answer: C
Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.
4. A client in an outpatient facility is taking Acarbose for type 2 Diabetes Mellitus. Which of the following laboratory tests should the nurse plan to monitor?
- A. WBC
- B. Serum potassium
- C. Platelet count
- D. Liver function test
Correct answer: D
Rationale: The correct answer is D: Liver function test. Acarbose, used for type 2 Diabetes Mellitus, can lead to liver toxicity with long-term use. Monitoring liver function tests periodically is crucial to detect any signs of liver dysfunction early and prevent complications. Choices A, B, and C are incorrect as Acarbose does not directly affect WBC, serum potassium, or platelet count levels.
5. A healthcare provider is reviewing a client's health record and notes that the client experiences permanent extrapyramidal effects caused by a previous medication. The healthcare provider should recognize that the medication affected which of the following systems in the client?
- A. Cardiovascular
- B. Immune
- C. Central nervous
- D. Gastrointestinal
Correct answer: C
Rationale: The correct answer is C: Central nervous. Extrapyramidal effects are movement disorders that can be caused by certain medications affecting the central nervous system, such as typical antipsychotic medications. These effects can lead to symptoms like tremors, muscle rigidity, and involuntary movements, which are all related to disruptions in the central nervous system. Choices A, B, and D are incorrect because extrapyramidal effects are specifically associated with the central nervous system and not the cardiovascular, immune, or gastrointestinal systems.
