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 Lovastatin. Which of the following instructions should be included?

• A. Take this medication on an empty stomach.
• B. Take this medication in the morning.
• C. Take this medication at bedtime.
• D. Increase your intake of potassium-rich foods.

Correct answer: C

Rationale: Lovastatin should be taken at bedtime because cholesterol production in the liver is highest at night, making the medication more effective in reducing cholesterol levels. By taking it at bedtime, the medication aligns with the body's natural rhythm of cholesterol synthesis, optimizing its therapeutic effects.

3. A client is prescribed an IM dose of penicillin. The client reports developing a rash after taking penicillin 3 years ago. What should the nurse do?

• A. Administer the prescribed dose.
• B. Withhold the medication.
• C. Ask the provider to change the prescription to an oral form.
• D. Administer an oral antihistamine at the same time.

Correct answer: B

Rationale: The nurse should withhold the medication and inform the provider of the client's previous rash after taking penicillin. This history suggests a potential allergic reaction to penicillin, which can range from mild to severe anaphylaxis. Notifying the provider allows for an alternative antibiotic to be prescribed, considering the client's allergy to penicillin. It is crucial to avoid administering a medication that could potentially lead to a severe allergic reaction in the client. Administering the prescribed dose (Choice A) could be harmful due to the potential for an allergic reaction. Changing the prescription to an oral form (Choice C) does not address the underlying issue of a potential penicillin allergy. Administering an oral antihistamine (Choice D) without consulting the provider may not be sufficient to prevent a severe allergic reaction.

4. A healthcare professional is reviewing laboratory findings and notes that a client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the healthcare professional?

• A. Perform immediate gastric lavage.
• B. Prepare the client for hemodialysis.
• C. Administer an additional oral dose of lithium.
• D. Request a stat repeat of the laboratory test.

Correct answer: A

Rationale: Performing immediate gastric lavage is the appropriate action for a client with severe lithium toxicity, indicated by a plasma lithium level of 2.1 mEq/L. Gastric lavage can help reduce the client's lithium level by removing the unabsorbed drug from the stomach.

5. A client has a new prescription for Calcitonin-salmon for postmenopausal osteoporosis. Which of the following instructions should the nurse include in the teaching?

• A. Swallow tablets on an empty stomach with plenty of water.
• B. Watch for skin rash and redness when applying calcitonin-salmon topically.
• C. Mix the liquid medication with juice and take it after meals.
• D. Alternate nostrils each time calcitonin-salmon is inhaled.

Correct answer: D

Rationale: Calcitonin-salmon is commonly administered intranasally for postmenopausal osteoporosis. It is essential to alternate nostrils daily when inhaling the medication to ensure equal distribution and optimal absorption. This technique helps prevent irritation and congestion in one nostril and enhances the effectiveness of the medication. Choices A, B, and C are incorrect because calcitonin-salmon is not swallowed, applied topically, or taken as a liquid medication after meals. Therefore, instructing the client to alternate nostrils during inhalation is the most appropriate teaching for this medication.
