Nursing Elites

1. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

2. A 2-year-old child diagnosed with HIV comes to a clinic for immunizations. Which of the following vaccines should the healthcare provider expect to administer in addition to the scheduled vaccines?

• A. pneumococcal vaccine
• B. hepatitis A vaccine
• C. Lyme disease vaccine
• D. typhoid vaccine

Correct answer: A

Rationale: The correct answer is the pneumococcal vaccine. Children with HIV are at increased risk of pneumococcal infections, so the pneumococcal vaccine is recommended as a supplemental vaccine for them. The hepatitis A vaccine is not routinely given to HIV-positive children unless they have other risk factors for hepatitis A. Lyme disease vaccine is for individuals at risk for Lyme disease, not routinely recommended for a 2-year-old. Typhoid vaccine is typically given to individuals traveling to endemic areas or working in settings with potential exposure to Salmonella typhi, not a routine vaccine for a 2-year-old with HIV.

3. A nurse is caring for an older client who has a bronchopulmonary infection. The nurse monitors the client's ability to maintain a patent airway because of which factor involved in the normal aging process?

• A. Increased respiratory system compliance
• B. Decreased number of alveoli and increased function of those remaining
• C. Decreased older client's ability to clear secretions
• D. Increased production of surfactant

Correct answer: C

Rationale: The correct answer is 'Decreased older client's ability to clear secretions.' Respiratory changes related to the normal aging process decrease an older adult's ability to clear secretions and protect the airway. In healthy older adults, the number of alveoli does not change significantly; their structure, however, is altered. Respiratory system compliance decreases with advancing age because of a progressive loss of elastic recoil of the lung parenchyma and conducting airways, and reduced elastic recoil of the lung and opposing forces of the chest wall. Production of surfactant in the lung does not usually decrease with aging, nor does it increase. However, the production of alveolar cells responsible for surfactant production is diminished. Choices A, B, and D are incorrect. Choice A is incorrect because respiratory system compliance decreases with aging. Choice B is incorrect as the number of alveoli does not significantly decrease in healthy older adults. Choice D is incorrect as the production of surfactant does not usually decrease with aging.

4. How should a client's neck be positioned for palpation of the thyroid?

• A. flexed toward the side being examined
• B. hyperextended directly backward
• C. flexed away from the side being examined
• D. flexed directly forward

Correct answer: A

Rationale: The correct way to position a client's neck for palpation of the thyroid is to have it flexed toward the side being examined. This positioning helps to better access and palpate the thyroid gland. Option B, hyperextending the neck directly backward, is incorrect as it can make palpation more difficult and uncomfortable for the client. Option C, flexing the neck away from the side being examined, is also incorrect as it may obscure the thyroid gland, making it harder to palpate. Option D, flexing the neck directly forward, is not ideal for thyroid palpation as it does not provide the best access to the gland.

5. 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.
