Correct Answer: A

Rationale: The correct answer is A: Temperature. A high temperature of 39.2°C (102°F) indicates a fever, which can be a sign of infection or another serious condition. Investigating the cause of the fever is a priority to address any underlying health issue promptly. Menses overdue (choice B) could be relevant but is not as urgent as addressing a fever. A soft tender abdomen (choice C) is important but may be a consequence of the underlying condition causing the fever. Heart rate (choice D) is also significant, but the priority here is to identify the cause of the fever.

Correct Answer: C

Rationale: The correct action for the nurse to take in this situation is to initiate contact precautions. MRSA (Methicillin-resistant Staphylococcus aureus) is a highly contagious bacterium that spreads through direct contact. Contact precautions involve wearing gloves and gowns to prevent the spread of infection to other patients or healthcare workers. Force-feeding oral fluids, requesting a nutrition consult, or limiting visitors to immediate family only are not the most appropriate actions in this scenario. These actions do not directly address the need to prevent the spread of MRSA, which is crucial in a healthcare setting.

Correct Answer: A

Rationale: The correct answer is A. Introducing solid foods one at a time, starting with cereal, is recommended to monitor for any food allergies or intolerances in infants. Choice B is incorrect as finely ground meat should be introduced later due to the risk of choking and is not necessary for iron intake. Choice C is incorrect as egg white should be avoided early due to the risk of allergies. Choice D is incorrect as solid foods should not be mixed with formula in a bottle to prevent overfeeding and promote healthy eating habits.

Correct Answer: B

Rationale: The correct answer is B. Petroleum jelly is flammable and should not be used with oxygen therapy due to the risk of fire. The client should avoid using petroleum-based products around oxygen equipment. Choices A, C, and D are all appropriate statements for a client with COPD receiving home oxygen therapy. Keeping the oxygen tank upright ensures proper oxygen flow, avoiding smoking or exposure to smoke helps prevent respiratory aggravation, and knowing to seek medical help promptly for breathing difficulties is essential for managing COPD effectively.

Correct Answer: D

Rationale: The correct answer is D: Blood glucose. Monitoring blood glucose levels is crucial for clients receiving total parenteral nutrition (TPN) due to the high glucose content in TPN solutions. TPN delivers essential nutrients, including glucose, directly into the bloodstream. Clients on TPN are at risk of developing hyperglycemia due to the concentrated glucose infusion. Therefore, close monitoring of blood glucose levels is necessary to detect and prevent hyperglycemia-related complications such as osmotic diuresis, hyperosmolarity, and electrolyte imbalances. While serum sodium, serum calcium, and blood urea nitrogen (BUN) levels are important parameters in various clinical scenarios, they are not specifically associated with TPN administration. These values are not the primary indicators to assess for complications in clients receiving TPN.
