Nursing Elites

1. When administering medications to a 4-month-old infant, which of the following pharmacokinetic principles should be considered? (Select all that apply.)

• A. Infants have a more rapid gastric emptying time.
• B. Infants have immature liver function.
• C. Infants' blood-brain barrier is poorly developed.
• D. Infants have an increased ability to absorb topical medications.

Correct answer: B

Rationale: When administering medications to a 4-month-old infant, the pharmacokinetic principle to consider is that infants have immature liver function until 1 year of age. This requires medications metabolized by the liver to be administered in smaller dosages. While infants do have a more rapid gastric emptying time, immature liver function is a more critical pharmacokinetic consideration in this context. Additionally, although infants have a poorly developed blood-brain barrier, this relates more to pharmacodynamic effects rather than pharmacokinetic principles. The statement about infants having an increased ability to absorb topical medications is not directly related to pharmacokinetic principles, making choice B the correct answer.

2. A client is starting therapy with rituximab. Which of the following findings should the nurse instruct the client to report?

• A. Dizziness
• B. Fever
• C. Urinary frequency
• D. Dry mouth

Correct answer: B

Rationale: The nurse should instruct the client to report fever when starting rituximab therapy. Fever can be a sign of infection, which is a potential complication associated with rituximab. Early detection and treatment of infections are important to ensure the client's safety and well-being. Dizziness, urinary frequency, and dry mouth are not commonly associated with rituximab therapy and are less likely to be directly related to the medication's side effects. Therefore, fever is the most crucial symptom to report to healthcare providers.

3. A client has a new prescription for Metformin. Which of the following adverse effects of Metformin should the nurse instruct the client to report to the provider?

• A. Somnolence
• B. Constipation
• C. Fluid retention
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A: Somnolence. Somnolence can indicate lactic acidosis, a rare but serious adverse effect of Metformin. Lactic acidosis is manifested by extreme drowsiness, hyperventilation, and muscle pain. Clients should be instructed to report these symptoms to their healthcare provider promptly to prevent further complications.

4. While caring for a client receiving IV heparin, which of the following findings should the nurse identify as an adverse effect of this medication?

• A. Hypertension
• B. Hyperglycemia
• C. Thrombocytopenia
• D. Leukopenia

Correct answer: C

Rationale: Thrombocytopenia, a decrease in platelet count, is a known adverse effect associated with heparin therapy. It can lead to an increased risk of bleeding and should be closely monitored during treatment. Choices A, B, and D are incorrect. Hypertension is not typically associated with heparin use; hyperglycemia is not a common adverse effect of heparin; leukopenia is not a primary side effect of heparin therapy.

5. When teaching a client with a prescription for Vancomycin, which instruction should the nurse include?

• A. Expect red man syndrome during treatment.
• B. Take the medication with a full glass of water.
• C. Increase your intake of potassium-rich foods.
• D. Monitor for hearing loss while taking this medication.

Correct answer: D

Rationale: The correct answer is D. Vancomycin is known to cause ototoxicity, which can result in hearing loss. Therefore, it is important for clients to monitor for any changes in their hearing while taking this medication and promptly report any issues to their healthcare provider for further evaluation and management. Choices A, B, and C are incorrect because red man syndrome is associated with rapid infusion of Vancomycin, not a common side effect during treatment; taking the medication with a full glass of water is a general instruction for many medications but not specific to Vancomycin; and increasing potassium-rich foods is not directly related to Vancomycin therapy.
