Nursing Elites

1. 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.

2. A client describes her cervical mucus as clear, thin, and elastic. Upon examination, the nurse demonstrates that the cervical mucus can be stretched 8-10 cm. The nurse correctly documents the finding as:

• A. increased ferning capacity.
• B. lack of ferning.
• C. spinnbarkheit.
• D. inhospitable.

Correct answer: C

Rationale: The nurse should document the finding as 'spinnbarkheit.' Spinnbarkheit is the term used to describe the clear, thin, and elastic cervical mucus that can be stretched 8-10 cm, indicating ovulation. It helps couples determine the most fertile period for conception. Ferning capacity or crystallization increases as ovulation approaches, but it requires microscopic examination to be confirmed. Lack of ferning cannot be determined without such examination. 'Inhospitable' cervical mucus refers to patterns that prohibit sperm motility, caused by various factors like hormone levels or infection. These conditions cannot be assessed based solely on the description provided in the question.

3. A client complains that her skin is redder than normal. The nurse notes the client's skin, documents hyperemia, and explains to the client that this condition is caused by which factor?

• A. Constriction of the underlying blood vessels
• B. An increased amount of bilirubin in the blood
• C. Increased perfusion of the surrounding tissues
• D. Excess blood in the dilated superficial capillaries

Correct answer: D

Rationale: Hyperemia is an excess of blood in a part of the body. The skin over a hyperemic area usually becomes reddened or warm. The condition is caused by increased blood flow, local relaxation of arterioles, or obstruction of the outflow of blood from an area. Choice A is incorrect because constriction of blood vessels would lead to decreased blood flow, not excess blood. Choice B is incorrect as an increased amount of bilirubin in the blood is related to jaundice, not hyperemia. Choice C is incorrect because increased perfusion of the surrounding tissues would cause redness, not hyperemia.

4. The nurse receives an order to administer phenytoin through the client's J-tube. The order instructs that tube feedings are stopped at least an hour prior to administering the medication and an hour after the medication is administered. Which of the following considerations may be a reason to discuss this order with the physician?

• A. The client has a history of Type II diabetes.
• B. The client is on a continuous tube-feeding regimen.
• C. The client is on fluid restriction.
• D. The pharmacy has provided phenytoin in tablet form.

Correct answer: B

Rationale: For a client on a continuous tube-feeding regimen, stopping tube feedings for two hours to administer this medication may compromise the client's nutritional status. This interruption can lead to inadequate nutrient intake, affecting the client's overall nutritional well-being. The other choices are less relevant in this situation. Type II diabetes does not directly impact the administration of phenytoin through a J-tube. Fluid restriction would not prevent the temporary interruption of tube feedings for medication administration. The form of phenytoin provided by the pharmacy does not impact the need to discuss the order with the physician regarding the client's continuous tube-feeding regimen.

5. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

• A. skin
• B. adipose tissue
• C. skeletal muscle
• D. myocardium

Correct answer: D

Rationale: The tissue that would receive the highest amount of cardiac output and thus the highest amount of a drug is the myocardium. Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being part of the heart, receives a significant amount of cardiac output. Choices A (skin) and B (adipose tissue) are poorly perfused tissues and would not receive high amounts of cardiac output. Choice C (skeletal muscle) is also less perfused compared to the myocardium.
