A client is on a mechanical ventilator. Which client response indicates that the neuromuscular blocker tubocurarine chloride (Tubarine) is effective?
- A. The client's extremities are paralyzed.
- B. The peripheral nerve stimulator causes twitching.
- C. The client clenches fist upon command.
- D. The client's Glasgow Coma Scale score is 14.
Correct Answer: A
Rationale: The correct answer is A because the neuromuscular blocker tubocurarine chloride causes muscle paralysis, leading to the extremities being paralyzed. This indicates that the medication is effectively blocking neuromuscular transmission.
B: Twitching with peripheral nerve stimulation indicates incomplete blockade.
C: Clenching fist upon command indicates preserved muscle strength.
D: Glasgow Coma Scale measures level of consciousness, not neuromuscular blockade.

A patient with bipolar disorder is prescribed valproic acid. What is an important side effect for the nurse to monitor?
- A. Hypertension
- B. Liver toxicity
- C. Hyperglycemia
- D. Bradycardia
Correct Answer: B
Rationale: Correct Answer: B (Liver toxicity)
Rationale:
1. Valproic acid is known to cause liver toxicity.
2. The nurse should monitor liver function tests regularly.
3. Signs of liver toxicity include jaundice, abdominal pain, and nausea.
4. Prompt detection is crucial to prevent serious complications.
Summary:
A: Hypertension - Not a common side effect of valproic acid.
C: Hyperglycemia - More commonly associated with other medications like antipsychotics.
D: Bradycardia - Not a typical side effect of valproic acid.
A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?
- A. Bounding erratic pulse.
- B. Regularly irregular pulse.
- C. Thready irregular pulse.
- D. No palpable pulse.
Correct Answer: D
Rationale: The correct answer is D: No palpable pulse. Ventricular fibrillation is a life-threatening arrhythmia where the heart quivers and doesn't effectively pump blood. This results in the absence of a palpable pulse. The nurse should anticipate this finding as it indicates a severe cardiac emergency requiring immediate intervention. Choices A, B, and C are incorrect because ventricular fibrillation leads to ineffective heart contractions, causing a lack of pulse rather than bounding, irregular, or thready pulses. It is crucial for the nurse to recognize the absence of a palpable pulse to initiate prompt resuscitative measures.
A patient with epilepsy is prescribed phenytoin. What is the primary side effect the nurse should monitor for?
- A. Hypotension
- B. Gingival hyperplasia
- C. Bradycardia
- D. Hyperkalemia
Correct Answer: B
Rationale: The correct answer is B: Gingival hyperplasia. Phenytoin is known to cause gingival overgrowth as a side effect. This is due to its effect on fibroblasts in the gums, leading to increased connective tissue production. Hypotension (A), bradycardia (C), and hyperkalemia (D) are not common side effects of phenytoin. Monitoring for gingival hyperplasia is crucial to prevent complications such as difficulty in eating, speaking, and maintaining oral hygiene.
A patient with diabetes insipidus is prescribed desmopressin. What is the primary purpose of this medication?
- A. Increase urine output
- B. Reduce blood sugar levels
- C. Decrease urine output
- D. Lower blood pressure
Correct Answer: C
Rationale: Desmopressin is a synthetic form of vasopressin used to replace the hormone in diabetes insipidus. The primary purpose is to decrease urine output by increasing water reabsorption in the kidneys, thereby reducing excessive urination and preventing dehydration. Choice A is incorrect as desmopressin actually decreases urine output. Choice B is incorrect as desmopressin does not directly affect blood sugar levels. Choice D is incorrect as desmopressin does not primarily lower blood pressure.
A patient with chronic kidney disease (CKD) is prescribed erythropoietin. What is the primary action of this medication?
- A. Stimulate white blood cell production
- B. Increase platelet count
- C. Promote red blood cell production
- D. Enhance clotting factor production
Correct Answer: C
Rationale: The correct answer is C: Promote red blood cell production. Erythropoietin is a hormone that stimulates the production of red blood cells in the bone marrow. This is crucial for patients with CKD who often develop anemia due to decreased erythropoietin production.
A: Stimulating white blood cell production is the function of other medications, such as colony-stimulating factors, not erythropoietin.
B: Erythropoietin does not have an effect on platelet count.
D: Enhancing clotting factor production is not the primary action of erythropoietin.
