1. What is a condition where the heart's valves do not function properly, leading to disrupted blood flow within the heart?
- A. Valvular heart disease
- B. Myocarditis
- C. Endocarditis
- D. Aneurysm
Correct answer: A
Rationale: Valvular heart disease is the correct answer. It occurs when the heart's valves malfunction, leading to disrupted blood flow within the heart. Myocarditis refers to inflammation of the heart muscle, not specifically related to valve function. Endocarditis is an infection of the inner lining of the heart chambers and valves, not necessarily caused by valve malfunction. Aneurysm is the abnormal bulging of a blood vessel, not directly related to heart valve function.
2. A nurse is planning care for a 2-month-old infant who is postoperative following surgical repair of a cleft lip. Which of the following actions should the nurse take?
- A. Position the infant on his abdomen
- B. Cleanse the incision site with hydrogen peroxide
- C. Offer the infant a pacifier
- D. Keep the infant's elbow restrained
Correct answer: D
Rationale: The nurse should keep the infant�s elbow restrained to prevent injury to the surgical site.
3. A patient is hospitalized due to nonadherence to an antitubercular drug treatment. Which of the following is most important for the nurse to do?
- A. Observe the patient taking the medications.
- B. Administer the medications parenterally.
- C. Instruct the family on the medication regimen.
- D. Count the number of tablets in the bottle daily.
Correct answer: A
Rationale: In this scenario, the most crucial action for the nurse to take is to observe the patient taking the medications. This ensures that the patient is actually consuming the prescribed antitubercular drugs, addressing the issue of nonadherence directly. Administering the medications parenterally (intravenously or intramuscularly) is not necessary unless there are specific medical reasons requiring this route of administration. Instructing the family on the medication regimen is important for support but may not directly address the patient's nonadherence. Counting the number of tablets in the bottle daily is not as effective as directly observing the patient taking the medications to ensure compliance.

5. A healthcare provider is providing care for a patient with generalized anxiety disorder (GAD) who has been prescribed an SSRI. Which SSRI is commonly used for this condition?
- A. Methylphenidate
- B. Sertraline
- C. Lithium
- D. Haloperidol
Correct answer: B
Rationale: The correct answer is B: Sertraline. Sertraline, an SSRI, is commonly used to treat generalized anxiety disorder (GAD) due to its efficacy and tolerability. Methylphenidate is a central nervous system stimulant used for ADHD and narcolepsy, not for GAD. Lithium is mainly used for bipolar disorder, not for GAD. Haloperidol is an antipsychotic medication, not typically used for GAD.
