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. 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.

3. What type of diet is appropriate for a client with chronic cirrhosis?

• A. High calorie, low protein
• B. High protein, high calorie
• C. Low fat, low sodium
• D. High calorie, low sodium

Correct answer: A

Rationale: The correct diet for a client with chronic cirrhosis is high calorie, low protein. Cirrhosis can lead to impaired protein metabolism, making it essential to limit protein intake. High-calorie foods help meet the client's energy needs. Choice B (High protein, high calorie) is incorrect because high protein intake can worsen hepatic encephalopathy. Choice C (Low fat, low sodium) is not the most appropriate diet for cirrhosis as the focus should be on calories and protein. Choice D (High calorie, low sodium) does not address the need to restrict protein intake, which is crucial in cirrhosis.

4. Which type of hepatitis is transmitted via the fecal-oral route?

• A. Hepatitis A
• B. Hepatitis B
• C. Hepatitis C
• D. Hepatitis D

Correct answer: A

Rationale: Hepatitis A is the correct answer because it is transmitted via the fecal-oral route, often through contaminated food or water. Hepatitis B is transmitted through exposure to infectious blood, semen, and other body fluids, not through the fecal-oral route. Hepatitis C is transmitted through blood-to-blood contact, not via the fecal-oral route. Hepatitis D occurs only in individuals infected with Hepatitis B. Therefore, the correct choice for the type of hepatitis transmitted via the fecal-oral route is Hepatitis A.

5. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?

• A. PaO2 90 mm Hg
• B. Bicarbonate 15 mEq/L
• C. CO2 47 mm Hg
• D. pH 7.34

Correct answer: B

Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.
