Nursing Elites

1. Which of the following lab values would indicate symptomatic AIDS in the medical chart? (T4 cell count per deciliter)

• A. Greater than 1000 cells per deciliter
• B. Less than 500 cells per deciliter
• C. Greater than 2000 cells per deciliter
• D. Less than 200 cells per deciliter

Correct answer: D

Rationale: A T4 cell count of less than 200 cells per deciliter indicates symptomatic AIDS. This severe depletion of T4 cells signifies advanced HIV infection and a significantly compromised immune system. Choices A, B, and C are incorrect because T4 cell counts above 2000, above 1000, or below 500 cells per deciliter, respectively, are not indicative of symptomatic AIDS.

2. A client is complaining of difficulty walking secondary to a mass in the foot. The nurse should document this finding as:

• A. Plantar fasciitis.
• B. Hallux valgus.
• C. Hammertoe.
• D. Morton's neuroma.

Correct answer: D

Rationale: The correct answer is Morton's neuroma. Morton's neuroma is a small mass or tumor in a digital nerve of the foot, causing pain and difficulty walking. Hallux valgus is commonly known as a bunion, involving a bony bump at the base of the big toe. Hammertoe is a condition where one toe is bent abnormally at the middle joint, resembling a hammer. Plantar fasciitis is characterized by pain and inflammation in the arch of the foot, not by a mass causing difficulty walking. Therefore, options A, B, and C are incorrect as they do not describe a mass in the foot leading to difficulty walking, unlike Morton's neuroma.

3. Which of the following observations is most important when assessing a client's breathing?

• A. presence of breathing and pulse rate
• B. breathing pattern and adequacy of breathing
• C. presence of breathing and adequacy of breathing
• D. patient position and adequacy of breathing

Correct answer: C

Rationale: The correct answer is the presence of breathing and adequacy of breathing. It is crucial not only to confirm that the client is breathing but also to ensure that the breathing is adequate for proper oxygenation. Choices A, B, and D are incorrect because while pulse rate, breathing pattern, and patient position are relevant aspects to consider, the most critical observations in assessing a client's breathing are the presence and adequacy of breathing.

4. The nurse teaching about preventable diseases should emphasize the importance of getting the following vaccines:

• A. human papillomavirus, genital herpes, measles.
• B. pneumonia, HIV, mumps.
• C. syphilis, gonorrhea, pneumonia.
• D. polio, pertussis, measles.

Correct answer: D

Rationale: Vaccines are one of the most effective methods of preventing and controlling certain communicable diseases. The smallpox vaccine is not currently in use because the smallpox virus has been declared eradicated from the world's population. Diseases such as polio, diphtheria, pertussis, and measles are mostly controlled by routine childhood immunization. They have not, however, been eradicated, so children need to be immunized against these diseases. Choices A, B, and C contain vaccines that do not protect against preventable diseases like polio, pertussis, and measles. Therefore, the correct choice is D.

5. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36mmHg, and HCO3 24 mEq/L?

• A. metabolic alkalosis
• B. homeostasis
• C. respiratory acidosis
• D. respiratory alkalosis

Correct answer: B

Rationale: The correct answer is 'homeostasis.' These ABG values fall within normal ranges, indicating a state of balance in the body's acid-base levels. Choices A, C, and D are incorrect as the ABG values provided do not point towards metabolic alkalosis, respiratory acidosis, or respiratory alkalosis. Instead, the values reflect a state of equilibrium where pH, PO2, PCO2, and HCO3 levels are within the normal range.
