ATI PN Comprehensive Predictor 2023

Correct Answer: D

Rationale: During a 12-lead ECG, the client needs to remain still to obtain accurate readings. Therefore, instructing the client to remain still is essential. Choices A, B, and C are incorrect because fasting is not necessary for an ECG, providing a warm blanket is not a standard procedure, and applying cold compresses may interfere with the ECG results.

Correct Answer: C

Rationale: The correct answer is C: 'Cut toenails straight across.' This instruction is crucial for clients with diabetes to prevent ingrown toenails and potential foot complications. Soaking feet in hot water daily (Choice A) can lead to skin damage and is not recommended for diabetic individuals. Using a heating pad on the feet daily (Choice B) can cause burns or injuries due to reduced sensation in the feet that often accompanies diabetes. Massaging feet with lotion daily (Choice D) is generally safe but may not address the specific preventive measure of cutting toenails correctly.

Correct Answer: B

Rationale: In clients with dementia, restlessness and agitation are important symptoms that the nurse should address first. These symptoms can indicate underlying issues such as pain, discomfort, or unmet needs, and addressing them promptly can prevent complications. Psychosocial stressors may contribute to the client's condition but should not be the initial priority. Frequent wandering at night and urinary incontinence are also common in dementia but do not pose immediate risks compared to restlessness and agitation.

Correct Answer: A

Rationale: The correct answer is A: Excessive thirst and fruity breath odor. Diabetic ketoacidosis presents with these early signs due to ketone buildup in the body. Choice B, weight loss and increased urination, are more characteristic of uncontrolled diabetes but not specific to diabetic ketoacidosis. Choice C, nausea and vomiting, can occur in diabetic ketoacidosis but are not as early or specific as excessive thirst and fruity breath odor. Choice D, hypoglycemia and fatigue, are not typical signs of diabetic ketoacidosis; rather, diabetic ketoacidosis usually presents with hyperglycemia.

Correct Answer: D

Rationale: In managing hyperkalemia, it is essential to administer insulin and glucose to shift potassium into the cells, restrict potassium intake to prevent further elevation of serum levels, and monitor the ECG for signs of potassium-induced cardiac effects. Therefore, the correct answer is D, as all of the provided actions are important in the management of hyperkalemia. Choice A alone is not sufficient as it only addresses shifting potassium intracellularly without preventing further elevation. Choice B alone is not enough as it does not address the immediate need to lower serum potassium levels. Choice C alone is insufficient as it only monitors for cardiac effects without addressing potassium levels or shifting mechanisms.
