1. Which of the following viruses is most likely to be acquired through casual contact with an infected individual?

• A. influenza virus
• B. herpes virus
• C. cytomegalovirus (CMV)
• D. human immunodeficiency virus (HIV)

Correct answer: A

Rationale: The correct answer is influenza virus. Influenza virus is most likely to be acquired through casual contact with an infected individual as it is transmitted through respiratory droplets. Herpes virus is primarily transmitted by direct contact, such as skin-to-skin contact, making it less likely to be acquired through casual contact. HIV is mainly transmitted through blood and body fluids like semen and vaginal fluids, not through casual contact. Cytomegalovirus (CMV) is an opportunistic infection commonly affecting immunocompromised individuals and is usually transmitted through close personal contact, not casual contact.

2. A 27-year-old woman has delivered twins in the OB unit. The patient develops a condition of 5-centimeter diastasis recti abdominis. Which of the following statements is the most accurate when instructing the patient?

• A. Avoid sit-ups to prevent worsening the condition.
• B. Surgery is not always necessary for this condition.
• C. Guarding the abdominal region is important at this time.
• D. Antibiotics are not needed for diastasis recti abdominis.

Correct answer: C

Rationale: After experiencing diastasis recti abdominis, it is crucial for the patient to protect and guard the abdominal region to facilitate healing. Choice A is correct since avoiding sit-ups is important to prevent worsening the condition by increasing intra-abdominal pressure. Choice B is accurate as not all cases of diastasis recti abdominis require surgery; conservative management is often effective. Choice D is also correct as antibiotics are not indicated for diastasis recti abdominis since it is a separation of the abdominal muscles and not an infectious condition.

3. A healthcare provider is caring for a patient who has experienced burns to the right lower extremity. According to the Rule of Nines, which of the following percentages most accurately describes the severity of the injury?

• A. 36%
• B. 27%
• C. 18%
• D. 9%

Correct answer: C

Rationale: According to the Rule of Nines, the right lower extremity accounts for 18% of the total body surface area. The Rule of Nines divides the body into regions, each representing 9% or a multiple of 9%, allowing for a quick estimation of the extent of burns. In this case, the correct answer is 18% as it corresponds to the percentage allocated for each lower extremity. Choices A, B, and D are incorrect as they do not match the standard allocation for the right lower extremity in the Rule of Nines.

4. Which physiologic mechanism best describes the function of the sodium-potassium pump?

• A. active transport
• B. diffusion
• C. filtration
• D. osmosis

Correct answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.

5. A patient has recently been prescribed Zidovudine (Retrovir). The patient has AIDS. Which of the following side effects should the patient specifically watch out for?

• A. Weakness and SOB
• B. Fever and anemia
• C. Hypertension and SOB
• D. Fever and hypertension

Correct answer: B

Rationale: The correct answer is 'Fever and anemia.' Zidovudine (Retrovir) is known to cause anemia as a side effect due to its impact on the bone marrow. Fever is also a common side effect associated with Zidovudine use. Therefore, the patient should watch out for these specific side effects. Choice A (Weakness and SOB) is incorrect as shortness of breath (SOB) is not a commonly reported side effect of Zidovudine. Choice C (Hypertension and SOB) and Choice D (Fever and hypertension) are unrelated to the known side effects of Zidovudine, making them incorrect.
