A nurse preparing to examine a client’s eyes plans to perform a confrontation test. The nurse tells the client that this test measures which aspect of vision?
- A. Near vision
- B. Color vision
- C. Distant vision
- D. Peripheral vision
Correct Answer: D
Rationale: The correct answer is D: Peripheral vision. The confrontation test is a gross measure of peripheral vision. It compares the client’s peripheral vision with the nurse’s, assuming that the nurse’s vision is normal. During the test, the nurse positions themselves at eye level with the client, about 2 feet away, and directs the client to cover one eye with an opaque card. The nurse covers the eye opposite the client’s covered one and slowly moves a target (like a pencil) from the periphery in several directions. The client is asked to indicate when they see the target, which should coincide with when the nurse sees it. Near vision is tested using a handheld vision screener with various sizes of print, color vision with the Ishihara test, and distant vision with a Snellen chart. Therefore, choices A, B, and C are incorrect as they do not measure peripheral vision, which is the focus of the confrontation test.

A nurse demonstrates the procedure for bathing a newborn to a new mother. The next day, the nurse watches as the mother bathes the infant. The nurse determines that the mother is performing the procedure correctly if the mother performs which action?
- A. Uses a cotton-tipped swab to carefully clean inside the infant's nose
- B. Uncovers only the body part being washed
- C. Washes the diaper area first
- D. Washes the infant's chest first
Correct Answer: B
Rationale: When bathing a newborn, it is crucial to follow a specific sequence for thorough cleaning and safety. The correct sequence includes starting with the eyes and face, then moving to the external ear, areas behind the ears, neck, hands, arms, legs, and finally the diaper area. Keeping the infant warm is essential, so only the body part being washed should be uncovered. Using a cotton-tipped swab to clean inside the infant's nose is not recommended due to the risk of injury if the infant moves suddenly. Washing the diaper area first is incorrect as it should be done towards the end of the bath to prevent contamination. Washing the infant's chest first is also incorrect as it deviates from the recommended bathing sequence for a newborn.
The nurse, assisting with data collection of the abdomen, inspects the client’s abdomen. Which assessment technique should the nurse perform next?
- A. Percussion
- B. Auscultation
- C. Light palpation
- D. Deep palpation
Correct Answer: B
Rationale: The correct answer is auscultation. The assessment techniques used for a physical examination are inspection, palpation, percussion, and auscultation. These techniques are normally performed in this order. However, in the abdominal examination, auscultation is performed after inspection and before palpation and percussion. This order is specific to the abdomen because palpation and percussion can increase peristalsis, leading to a false interpretation of bowel sounds. Therefore, auscultation is performed before palpation and percussion in abdominal assessments to ensure accurate bowel sound assessment. Percussion and palpation are performed after auscultation in abdominal assessments. Choices A, C, and D are incorrect as auscultation is the next assessment technique to perform after inspection in abdominal assessments, followed by palpation and percussion.
A woman is receiving oxytocin to induce labor. Which action should the nurse take first upon noting the presence of late decelerations on the fetal heart rate (FHR) monitor?
- A. Notifying the healthcare provider
- B. Stopping the oxytocin infusion
- C. Checking the woman's blood pressure and pulse
- D. Increasing the intravenous (IV) rate of the nonadditive solution
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.
A nurse assisting with data collection is testing the cochlear portion of the acoustic nerve (cranial nerve VIII). Which action does the nurse take to test this nerve?
- A. Asking the client to raise their eyebrows and looking for symmetry
- B. Asking the client to clench the teeth, then palpating the masseter muscles just above the mandibular angle
- C. Asking the client to close the eyes and then identify light and sharp touch with a cotton ball and a pin on both sides of the face
- D. Asking the client to close their eyes and then indicate when a ticking watch is heard as the nurse brings the watch closer to the client's ear
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).
What is a chemical reaction between drugs before their administration or absorption known as?
- A. a drug incompatibility
- B. a side effect
- C. an adverse event
- D. an allergic response
Correct Answer: A
Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly occurs when drug solutions are mixed before intravenous administration but can also happen with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses typically occur after the drugs have been administered and absorbed, not before.
