1. A client has a prescription for gentamicin for the treatment of an infection. Which finding indicates a potential adverse reaction to the medication?

A. Blood pressure 160/90 mm Hg
B. Presence of red blood cells in the urine
C. Urine output of 35 mL/hr
D. Respiratory rate of 22/min

Correct answer: B

Rationale: The presence of red blood cells in the urine can indicate nephrotoxicity, which is a potential adverse effect of gentamicin. Gentamicin can cause damage to the kidneys, leading to the presence of red blood cells in the urine as a sign of renal impairment. Monitoring for this finding is crucial to detect and manage adverse reactions promptly. High blood pressure (Choice A) is not typically associated with gentamicin use. Low urine output (Choice C) is more suggestive of kidney injury rather than nephrotoxicity specifically related to gentamicin. Respiratory rate (Choice D) is not a common indicator of adverse reactions to gentamicin.

2. Which of the following drugs is associated with Stevens-Johnson syndrome?

A. Valproic acid
B. Quinidine
C. Isoniazid
D. Ethosuximide

Correct answer: D

Rationale: Stevens-Johnson syndrome is a severe skin reaction that can be associated with Ethosuximide.

3. What is the antidote for Warfarin?

A. Naloxone
B. Vitamin K
C. Glucagon
D. Vitamin B

Correct answer: B

Rationale: The correct antidote for Warfarin is Vitamin K. Warfarin works by inhibiting vitamin K-dependent clotting factors. Administering Vitamin K helps reverse its effects by replenishing these factors. Choices A, C, and D are incorrect. Naloxone is used to reverse opioid overdose, Glucagon is used to treat severe low blood sugar, and Vitamin B is not the antidote for Warfarin.

4. A client with increased liver enzymes is taking herbal supplements. Which of the following herbal supplements should the nurse report to the provider?

A. Glucosamine
B. Saw palmetto
C. Kava
D. St. John's wort

Correct answer: C

Rationale: The nurse should report kava to the provider because chronic use or high doses of kava can lead to liver damage, including severe liver failure. It is crucial for the nurse to be vigilant about any herbal supplement that could potentially worsen the client's liver condition.

5. A healthcare professional is reviewing a new prescription for Ondansetron 4 mg PO PRN for nausea and vomiting for a client who has Hyperemesis Gravidarum. The healthcare professional should clarify which of the following parts of the prescription with the provider?

A. Name
B. Dosage
C. Route
D. Frequency

Correct answer: D

Rationale: The prescription lacks the frequency of medication administration, which is crucial for ensuring appropriate use. In this case, the frequency of when the medication can be taken needs to be clarified with the provider to provide safe and effective care for the client with Hyperemesis Gravidarum.
