Correct Answer: B

Rationale: The axillary method is the most appropriate for newborns because it is non-invasive and safe. Rectal temperature measurement can be uncomfortable and poses a risk of injury, especially in newborns. Oral temperature measurement is not recommended for newborns due to their inability to cooperate and potential inaccuracies. Tympanic temperature measurement may not be as accurate in newborns compared to older children or adults.

Correct Answer: C

Rationale: The correct answer is C: 'Take up to three tablets during a single angina episode.' Nitroglycerin can be taken up to three times during an episode to relieve angina. Choice A is incorrect because the client should place the tablet under the tongue and wait for it to dissolve, not wait for 10 minutes. Choice B is incorrect because taking up to five tablets during an angina episode is excessive and not recommended. Choice D is incorrect because nitroglycerin tablets are meant to be taken sublingually, not swallowed.

Correct Answer: A

Rationale: The correct answer is to ensure the blood is compatible with the recipient's blood type. This is crucial to prevent transfusion reactions, which can be life-threatening. Choice B is incorrect because warming blood to body temperature is not a standard practice and may lead to hemolysis. Choice C is incorrect as blood products are carefully screened for clots before distribution. Choice D is incorrect because it is not necessary for the recipient to eat before a blood transfusion.

Correct Answer: C

Rationale: When signs of phlebitis are observed in a client receiving IV fluids, the appropriate action is to apply a warm compress. This helps to reduce discomfort and swelling at the site of the IV insertion. Applying a cold compress may not be as effective in this case and could potentially worsen the condition. While notifying the physician is important, providing immediate comfort to the client through a warm compress is the initial recommended intervention. Administering anti-inflammatory medication should only be done under the direction of a healthcare provider after assessment and evaluation of the client's condition.

Correct Answer: A

Rationale: The most appropriate intervention for a client with left-leg weakness learning to use a cane is to maintain two points of support on the floor at all times. This ensures stability and helps distribute weight evenly between the legs, reducing the risk of falls. Using the cane on the weak side of the body (Choice B) may not provide adequate support. Advancing the cane and the strong leg simultaneously (Choice C) can lead to imbalance and increases the risk of falls. Advancing the cane too far with each step (Choice D) can also compromise balance and stability.
