Nursing Elites

1. What effect can medication bound to protein have?

• A. reduced drug availability
• B. limited distribution of the drug to receptor sites
• C. less availability to produce desired medicinal effects
• D. decreased metabolism of the drug by the liver

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

2. A client with Kawasaki disease has bilateral congestion of the conjunctivae, dry cracked lips, a strawberry tongue, and edema of the hands and feet followed by desquamation of fingers and toes. Which of the following nursing measures is most appropriate to meet the expected outcome of positive body image?

• A. administering immune globulin intravenously
• B. assessing the extremities for edema, redness, and desquamation every 8 hours
• C. explaining progression of the disease to the client and their family
• D. assessing heart sounds and rhythm

Correct answer: C

Rationale: Educating the client and their family about the progression of Kawasaki disease is crucial for promoting a positive body image. By explaining when symptoms are expected to improve and resolve, the client and family can better understand that there will be no permanent disruption in physical appearance that could negatively impact body image. Administering immune globulin intravenously is a treatment for Kawasaki disease but does not directly address body image concerns. Assessing the extremities for edema, redness, and desquamation every 8 hours is important for monitoring the disease but does not directly address body image concerns. Assessing heart sounds and rhythm is essential for evaluating cardiac effects of Kawasaki disease but is not the most direct measure for promoting a positive body image.

3. A client, age 28, is 8 1/2 months pregnant. She is most likely to display which normal skin-color variation?

• A. vitiligo
• B. erythema
• C. cyanosis
• D. chloasma

Correct answer: D

Rationale: Chloasma, also known as the mask of pregnancy, is described as tan-to-brown patches on the face. This hyperpigmentation results from hormonal changes during pregnancy. Vitiligo is characterized by depigmented patches, erythema is redness of the skin due to increased blood flow, and cyanosis is a bluish discoloration due to poor circulation or lack of oxygen, none of which are typical skin-color variations during pregnancy. Therefore, in a pregnant client, the most likely normal skin-color variation to be displayed is chloasma.

4. 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.

5. A nurse assisting with data collection is preparing to auscultate for bowel sounds. The nurse should use which technique?

• A. Begin in the right lower quadrant.
• B. Use the bell end of the stethoscope.
• C. Hold the stethoscope lightly against the skin.
• D. Listen for at least 5 minutes before deciding that bowel sounds are absent.

Correct answer: A

Rationale: To auscultate for bowel sounds, the nurse should use the diaphragm end piece of the stethoscope as bowel sounds are relatively high pitched. The stethoscope should be held lightly against the skin to avoid stimulating more bowel sounds. The nurse should begin in the right lower quadrant at the ileocecal valve, where bowel sounds are normally present. It is recommended to listen for 5 minutes before deciding that bowel sounds are absent to ensure a thorough assessment. Choice B is incorrect because the bell end is used for low-pitched sounds such as heart sounds. Choice C is incorrect as holding the stethoscope firmly and deeply can cause unnecessary bowel sound stimulation. Choice D is incorrect as listening for 1 minute is insufficient to determine the presence or absence of bowel sounds.
