Correct Answer: D

Rationale: The correct answer is cranial nerve XII (hypoglossal nerve). When testing cranial nerve XII, the healthcare provider inspects the symmetry and movement of the tongue. The tongue should protrude in the midline when the client sticks it out. Cranial nerve IX (glossopharyngeal nerve) and X (vagus nerve) are tested by depressing the tongue with a blade to observe pharyngeal movement and gag reflex. Cranial nerve V (trigeminal nerve) is responsible for testing the muscles of mastication, not tongue protrusion.

Correct Answer: C

Rationale: The correct answer is a client who states they are not interested. While lack of interest can hinder learning motivation, it is not a physical or mental barrier that directly impacts the learning process. On the other hand, a client who took Ambien® an hour ago may experience drowsiness or impaired cognitive function, affecting their ability to learn. A bipolar client in a manic phase may exhibit symptoms such as racing thoughts, distractibility, and impulsivity, making it challenging for them to focus and engage in the learning process. A client with dysphagia may have difficulty swallowing, which can interfere with their ability to take oral medications or participate in activities that involve swallowing.

Correct Answer: A

Rationale: To measure a client's calf circumference accurately, a nurse should place a non-stretchable tape measure around the widest point of the lower leg. It is crucial to ensure that the tape measure is positioned at the same number of centimeters down from a specific landmark, such as the patella, on both legs for consistency. Placing the tape measure 2 inches above the knee (Option B), 2 inches above the ankle (Option C), or 2 inches below the patella (Option D) would not provide an accurate measurement of the calf circumference. Therefore, these options are incorrect choices.

Correct Answer: D

Rationale: The correct answer is Fluoxetine. Among the options provided, Fluoxetine is the medication least likely to cause tinnitus. Gentamicin, Lasix, and Aspirin are known ototoxic medications that have a potential side effect of causing tinnitus, a ringing in the ear. Gentamicin is an antibiotic, Lasix is a diuretic, and Aspirin is a common pain reliever that can lead to tinnitus. In contrast, Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) primarily used as an antidepressant, and it has a lower risk of causing tinnitus compared to the other options.

Correct Answer: A

Rationale: Primary prevention involves activities that promote wellness or prevent illness or injury. Educating parents about safety measures in the home aims to prevent injuries, making it a primary prevention strategy. Secondary prevention focuses on early detection and intervention in diseases or injuries. Tertiary prevention involves reducing disability and promoting optimal functioning in relation to a disease or injury. Health promotion encompasses activities that enhance a client's overall health and well-being. In this scenario, educating parents about safety in the home falls under primary prevention as it aims to prevent injuries before they occur.
