Correct Answer: B

Rationale: When late decelerations are noted on the fetal heart rate (FHR) monitor during oxytocin infusion, it indicates decreased oxygenation to the fetus. The immediate action the nurse should take is to stop the oxytocin infusion. This helps reduce uterine activity, increase fetal oxygenation, and prevent further stress on the fetus. Stopping the oxytocin infusion is crucial to address the underlying issue causing the late decelerations. Checking the woman's blood pressure and pulse, increasing the IV rate of the nonadditive solution, or notifying the healthcare provider can be important actions but are secondary to stopping the oxytocin infusion in this scenario.

Correct Answer: D

Rationale: To test the cochlear portion of the acoustic nerve (cranial nerve VIII), the nurse should have the client close their eyes and indicate when a ticking watch is heard as the nurse moves the watch closer to the client's ear. This action assesses the client's ability to perceive auditory stimuli, as the cochlear portion of the acoustic nerve is responsible for hearing. Choices A, B, and C are incorrect. Asking the client to raise their eyebrows to check for symmetry is a method to test the facial nerve (cranial nerve VII). Asking the client to clench their teeth and palpating the masseter muscles tests the motor component of the trigeminal nerve. Having the client identify light and sharp touch on both sides of the face is a way to test the sensory component of the trigeminal nerve (cranial nerve V).

Correct Answer: A

Rationale: When percussing a full bladder, the nurse expects to note dull sounds over the symphysis pubis. This is because a full bladder produces a flat or dull sound. Hyperresonance sounds are present with gaseous distention of the abdomen, not a full bladder. Bowel sounds are auscultated, not percussed, so hypoactive bowel sounds or an absence of bowel sounds are unrelated findings when assessing bladder distention.

Correct Answer: B

Rationale: Melena' is the term used to describe abnormal black tarry stool that has a distinctive odor and contains digested blood. It usually results from bleeding in the upper gastrointestinal tract and is often a sign of peptic ulcer disease or small bowel disease. The presence of melena is detected by checking the client's stool for blood. Blood in the client's urine, decreased urine output, and diarrhea are not associated with the assessment for melena.

Correct Answer: A

Rationale: When preparing the physical environment for an interview with a client, it is crucial to ensure the client's comfort. Setting the room temperature at a comfortable level is essential for the client's well-being. Additionally, providing privacy, sufficient lighting, and removing distractions are crucial factors. It is recommended to maintain a distance of around 4 to 5 feet between the client and the nurse. Seating should be arranged so that the client and nurse are at eye level to facilitate effective communication and prevent barriers. Placing a chair across from the nurse's desk may create a physical barrier, positioning the client to face a strong light can be uncomfortable and distracting, and setting up seating so that the client and nurse are not at eye level may impede effective communication.
