1. Which of the following is the antidote for Heparin toxicity?

A. Protamine
B. Methylene blue
C. N-acetylcysteine
D. Glucagon

Correct answer: A

Rationale: Protamine is the specific antidote for Heparin toxicity. Heparin is an anticoagulant medication, and if an overdose occurs or if there is excessive bleeding due to Heparin use, protamine, a positively charged molecule, can neutralize the anticoagulant effects of Heparin by forming a complex with it. This binding prevents Heparin from further inhibiting coagulation factors and helps in reversing its effects.

2. A client has a new prescription for Methotrexate. Which of the following instructions should be included in the teaching?

A. Avoid drinking alcohol while taking this medication.
B. Take the medication with a high-fat meal.
C. Expect increased hair growth.
D. You should never stop taking the medication without consulting your healthcare provider.

Correct answer: A

Rationale: The correct instruction for a client taking Methotrexate is to avoid drinking alcohol. Methotrexate can cause liver toxicity, and alcohol consumption can increase this risk. It is important to emphasize the avoidance of alcohol while on this medication to prevent adverse effects and ensure treatment effectiveness. The other options are incorrect: Taking Methotrexate with a high-fat meal is not necessary as it can be taken with or without food. Increased hair growth is not an expected effect of Methotrexate; in fact, hair loss is a potential side effect. Stopping the medication without consulting a healthcare provider can be dangerous and may lead to worsening of symptoms or relapse, making option D incorrect.

3. When teaching parents about a child newly prescribed Desipramine, the nurse should instruct them that which of the following adverse effects is the priority to report to the provider?

A. Constipation
B. Suicidal thoughts
C. Photophobia
D. Dry mouth

Correct answer: B

Rationale: The priority adverse effect to report when a child is prescribed Desipramine is suicidal thoughts. Desipramine can increase the risk of suicidal thoughts and behaviors. It is crucial for parents to monitor the child for any signs of worsening depression or thoughts of self-harm and report them promptly to the healthcare provider to prevent any harm to the child. Options A, C, and D are potential side effects of Desipramine but are not as urgent or life-threatening as suicidal thoughts, which require immediate intervention to ensure the safety of the child.

4. What is the action of Metformin?

A. Decreasing intestinal glucose absorption
B. Increasing sensitivity to insulin
C. Decreasing hepatic glucose production
D. All of the above

Correct answer: D

Rationale: Metformin exerts its effects by decreasing hepatic glucose production, increasing sensitivity to insulin, and decreasing intestinal glucose absorption. These actions help in lowering blood glucose levels and improving insulin sensitivity in individuals with diabetes.

5. A healthcare provider is caring for a client who is prescribed Furosemide. Which of the following laboratory values should the healthcare provider monitor?

A. Serum potassium
B. Serum calcium
C. Serum sodium
D. Serum magnesium

Correct answer: A

Rationale: Furosemide is a loop diuretic that can cause hypokalemia (low potassium levels) due to increased potassium excretion in the urine. Monitoring serum potassium levels is crucial to prevent complications such as cardiac arrhythmias. Therefore, the healthcare provider should closely monitor the client's serum potassium levels when they are prescribed Furosemide. While monitoring other electrolytes like sodium and magnesium may also be important in certain situations, the priority for a client prescribed Furosemide is to monitor serum potassium levels due to the risk of hypokalemia.
