Correct Answer: A

Rationale: The correct answer is A because wearing a mask in public can help prevent the spread of TB to others. Choice B is incorrect as taking medication as prescribed helps in treating the infection within the individual but does not directly prevent spreading it to others. Choice C is important for respiratory hygiene but may not be sufficient to prevent transmission. Choice D, isolation until treatment is complete, is crucial for preventing the spread but is not specifically about understanding transmission.

Correct Answer: B

Rationale: When administering enteral feeding through a jejunostomy tube, the nurse should administer the formula continuously. Continuous feeding is essential for optimal nutrient absorption and to prevent complications. Administering the formula every four to six hours, in a bolus, or every hour may lead to inadequate nutrition, improper absorption, and an increased risk of complications such as aspiration or dumping syndrome, making these choices incorrect.

Correct Answer: C

Rationale: The correct answer is C. Infants should not consume more than 24 ounces of milk a day as it can lead to iron deficiency anemia and other issues. Choices A and B demonstrate appropriate dietary choices for a 9-month-old, as they involve providing the infant with family foods and appropriate finger foods. Choice D is also appropriate as it shows the infant is transitioning to drinking from a cup.

Correct Answer: C

Rationale: The correct answer is C. Eating crackers before getting out of bed can help manage nausea associated with hyperemesis gravidarum. Choice A is incorrect because drinking water with meals may exacerbate nausea. Choice B is incorrect as eating every 6 hours may not be frequent enough to combat nausea and vomiting. Choice D is incorrect because protein intake should not be limited during pregnancy, especially in cases of hyperemesis gravidarum.

Correct Answer: C

Rationale: Checking the client's gag reflex before eating or drinking is the highest priority for a client at risk for aspiration pneumonia. Aspiration pneumonia can occur when food, liquids, or saliva are inhaled into the lungs, leading to inflammation or infection. Checking the gag reflex helps prevent the aspiration of substances into the lungs. Assessing the client's level of consciousness (Choice A) is important but not as immediately critical as checking the gag reflex. Monitoring oxygen saturation (Choice B) is essential for respiratory assessment but does not directly prevent aspiration. Monitoring intake and output (Choice D) is important for overall client management but does not specifically address the risk of aspiration pneumonia.
