Question 1 of 5
The nurse is assessing a client on a telemetry unit when the client states, "My vision is blurry, and I have been seeing yellow/green halos everywhere I look." Which of the following would the nurse suspect?
Correct Answer: D
Rationale: The correct answer is D: Digoxin (Lanoxin) toxicity. Blurred vision and seeing yellow/green halos are classic signs of digoxin toxicity. Digoxin can cause visual disturbances due to its effects on the optic nerve. Hyperglycemia (choice
A) typically does not present with visual disturbances. Captopril (choice
B) and Verapamil (choice
C) do not typically cause visual changes like halos. Digoxin toxicity (choice
D) is the most likely cause based on the client's symptoms.
Question 2 of 5
The nurse is teaching a client who has been diagnosed with hyperlipidemia about medication therapy. Which of the following medications should the nurse include in the teaching?
Correct Answer: A
Rationale:
Rationale: Lovastatin (Mevacor) is a statin medication used to lower cholesterol levels in hyperlipidemia. It inhibits an enzyme involved in cholesterol synthesis, thus reducing LDL levels. This makes it an appropriate choice for managing hyperlipidemia. Pioglitazone (Actos) is used for diabetes, Spironolactone (Aldactone) for hypertension and heart failure, and Nitrofurantoin (Macrodantin) for urinary tract infections.
Therefore, only option A directly addresses hyperlipidemia.
Question 3 of 5
A client is brought to the emergency department in acute alcohol withdrawal. Which of the following medications does the nurse anticipate will be ordered to prevent seizures and delirium tremens?
Correct Answer: C
Rationale: The correct answer is C: Diazepam [Valium]. Diazepam is a benzodiazepine used to treat alcohol withdrawal symptoms by preventing seizures and delirium tremens. It acts by enhancing the inhibitory effects of GABA in the brain, reducing excitability and preventing withdrawal symptoms. Zolpidem (
A) is a sedative-hypnotic but not used for alcohol withdrawal. Morphine (
B) is an opioid analgesic and can worsen alcohol withdrawal. Fluoxetine (
D) is an antidepressant and not indicated for acute alcohol withdrawal.
Question 4 of 5
A client is admitted to a hospital for treatment for first-time acute symptoms of mania. The nurse anticipates the provider will prescribe which of the following medications?
Correct Answer: A
Rationale: The correct answer is A: Lithium [Lithobid]. Lithium is a mood stabilizer commonly used to treat acute symptoms of mania. It helps in reducing manic episodes and stabilizing mood swings. Diazepam (
B) is a benzodiazepine used for anxiety and not recommended for mania. Bupropion (
C) is an antidepressant and not ideal for mania. Paroxetine (
D) is also an antidepressant and not the first-line treatment for mania.
Question 5 of 5
The nurse is screening a client with a new prescription for beta blocker adrenergic propranolol [Inderal LA]. The nurse recognizes that this medication is contraindicated in the presence of which of the following conditions?
Correct Answer: C
Rationale: The correct answer is C: Asthma. Propranolol is contraindicated in asthma because it can cause bronchospasm due to its non-selective beta-blocking effects on both beta-1 and beta-2 receptors in the lungs. This can worsen respiratory function and potentially lead to an asthma exacerbation. Angina (choice
A) is often a reason for prescribing beta blockers. Tachycardia (choice
B) can also be managed with beta blockers. Gout (choice
D) is not a contraindication for propranolol use.
