1. What is a serious adverse reaction to penicillin?

A. Liver Failure
B. Anaphylaxis
C. Respiratory Depression
D. Edema

Correct answer: B

Rationale: The correct answer is B: Anaphylaxis. Anaphylaxis is a severe allergic reaction that can occur as a serious adverse reaction to penicillin. It is a life-threatening condition that requires immediate medical attention. Choices A, C, and D are incorrect. Liver failure is not a typical adverse reaction to penicillin, respiratory depression is more commonly associated with opioid medications, and edema is not a common severe adverse reaction to penicillin.

2. A healthcare professional is reviewing the medication administration record for a client who is receiving transdermal Fentanyl for severe pain. Which of the following medications should the healthcare professional expect to cause an adverse effect when administered concurrently with Fentanyl?

A. Ampicillin
B. Diazepam
C. Furosemide
D. Prednisone

Correct answer: B

Rationale: Diazepam, a CNS depressant, can interact with Fentanyl causing severe sedation when administered concurrently. This is due to the additive central nervous system depressant effects of both medications, which can lead to excessive sedation, respiratory depression, and other serious adverse effects. Therefore, healthcare professionals need to monitor clients closely for signs of excessive sedation or respiratory depression when administering these medications together.

3. What is the antidote for Warfarin?

A. Vitamin D
B. Vitamin C
C. Vitamin K
D. Vitamin B6

Correct answer: C

Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.

4. A client has a prescription for Prednisone for the treatment of Rheumatoid Arthritis. Which of the following statements by the client indicates an understanding of the teaching?

A. I will increase my intake of potassium-rich foods.
B. I should take my medication with food.
C. I will decrease my intake of calcium-rich foods.
D. I should avoid eating grapefruit while taking this medication.

Correct answer: A

Rationale: The correct answer is A. Prednisone can cause hypokalemia, leading to low potassium levels. Increasing the intake of potassium-rich foods helps prevent this imbalance. Choices B, C, and D are incorrect because taking Prednisone with food, decreasing calcium-rich foods, or avoiding grapefruit are not specifically related to addressing the side effect of hypokalemia associated with Prednisone.

5. A client has a new prescription for Metformin to treat type 2 diabetes. Which of the following laboratory results should be monitored?

A. Hemoglobin A1C
B. Liver function tests
C. Electrolyte levels
D. Kidney function

Correct answer: D

Rationale: Metformin is excreted by the kidneys, and impaired kidney function can lead to an increased risk of lactic acidosis, a serious side effect. Therefore, it is important to monitor kidney function regularly while a client is on Metformin. Hemoglobin A1C is used to monitor long-term glucose control, but kidney function is the priority for monitoring Metformin therapy.
