Nursing Elites

1. A nurse assisting with data collection of the peripheral vascular system performs the Allen test. The nurse understands that this test is used to determine the patency of which blood vessel(s)?

• A. Capillaries
• B. Pedal pulses
• C. Femoral arteries
• D. Radial and ulnar arteries

Correct answer: D

Rationale: The nurse performs the Allen test to determine the patency of the radial and ulnar arteries. During the test, the nurse applies pressure over the client's ulnar and radial arteries simultaneously. The client is then asked to open and close the hand repeatedly, causing the hand to blanch. Subsequently, the nurse releases pressure from the ulnar artery while compressing the radial artery and checks the color of the extremity distal to the pressure point. If pinkness fails to return within 6 seconds, it indicates that the ulnar artery is insufficient, suggesting that the radial artery should not be used for obtaining a blood specimen. Choice A (Capillaries) is incorrect as the Allen test assesses the patency of larger arteries, not capillaries. Choice B (Pedal pulses) is incorrect as the Allen test specifically evaluates the radial and ulnar arteries, not the pedal pulses in the foot. Choice C (Femoral arteries) is incorrect as the Allen test focuses on the radial and ulnar arteries in the hand, not the femoral arteries in the leg.

2. A nurse is preparing to screen a client's vision with the use of a Snellen chart. The nurse uses which technique?

• A. Tests the right eye, then tests the left eye, and finally tests both eyes together
• B. Assesses both eyes together, then assesses the right and left eyes separately
• C. Asks the client to stand 40 feet from the chart and read the largest line on the chart
• D. Asks the client to stand 40 feet from the chart and read the line that can be read 200 feet away by someone with unimpaired vision

Correct answer: A

Rationale: To test visual acuity with the use of a Snellen chart, the nurse places the chart in a well-lit spot at the client's eye level, with the client positioned exactly 20 feet from the chart. The client shields one eye at a time with an opaque card during the test. After testing each eye separately, both eyes are assessed together. The client is asked to read the smallest line of letters visible and encouraged to read the next smallest line as well. Therefore, option A is correct as it describes the correct technique of testing one eye at a time before assessing both eyes together. Option B is incorrect as it assesses both eyes together first, which is not the standard procedure. Options C and D are incorrect as they suggest standing 40 feet from the chart, which contradicts the standard distance of 20 feet for a Snellen chart test.

3. A nurse in the newborn nursery, assisting with data collection for a newborn, prepares to measure the chest circumference. The nurse places the tape measure around the infant at which location?

• A. In the axillary area
• B. At the level of the nipples
• C. Two inches below the nipples
• D. At the level of the umbilicus

Correct answer: B

Rationale: The chest circumference of the infant is measured at the level of the nipples. It is usually 2 to 3 cm smaller than the head circumference. The average chest circumference is 30.5 to 33 cm (12-13 inches). When there is molding of the head, the head and chest measurements may be equal at birth. Placing the tape measure at the level of the nipples ensures accuracy and consistency in newborn assessment. Options A, C, and D are incorrect as the chest circumference is specifically measured at the level of the nipples to obtain precise measurements.

4. Which of the following methods of contraception is able to reduce the transmission of HIV and other STDs?

• A. intrauterine device (IUD)
• B. Norplant
• C. oral contraceptives
• D. vaginal sponge

Correct answer: D

Rationale: The correct answer is the vaginal sponge. The vaginal sponge is a barrier method of contraception that, when used with foam or jelly contraception, reduces the transmission of HIV and other STDs, as well as reducing the risk of pregnancy. Intrauterine devices (IUDs), Norplant, and oral contraceptives can prevent pregnancy but not the transmission of HIV and STDs. Clients using the contraceptive methods in Choices A, B, and C should be counseled to use a chemical or barrier contraceptive to decrease the transmission of HIV or STDs.

5. A woman who delivered a healthy newborn 6 hours earlier complains of discomfort at the episiotomy site. Which action by the nurse is the most appropriate?

• A. Administering an intravenous (IV) opioid analgesic
• B. Assisting the woman in taking a warm sitz bath
• C. Applying an ice pack to the perineum
• D. Contacting the registered nurse

Correct answer: C

Rationale: Applying an ice pack to the perineum is the most appropriate action in this scenario. Ice causes vasoconstriction, providing relief by numbing the area and preventing edema. It is typically used within the first 12 to 24 hours after birth. Assisting the woman in taking a warm sitz bath is more suitable after 24 hours as warm water can be soothing. Administering an IV opioid analgesic is excessive; an anesthetic spray is more appropriate for surface discomfort. Contacting the registered nurse is unnecessary as applying an ice pack is within the nurse's scope and can effectively address the discomfort without escalation.
