Correct Answer: D

Rationale: The correct answer is D. Keeping the side rails of a toddler's crib elevated is an appropriate use of restraints to prevent the child from falling, which is an essential safety measure. Placing a belt restraint on a school-age child with seizures (choice A) is not recommended as it can be dangerous during a seizure. Securing wrist restraints to the bed rails for an adolescent (choice B) may cause harm and should not be done routinely. Applying elbow immobilizers to an infant receiving a cleft lip injury (choice C) is not a standard practice for managing this condition and would not be appropriate.

Correct Answer: D

Rationale: The correct answer is D. A blood glucose level of 110 mg/dL indicates that the TPN is effective in maintaining normal glucose levels. Hemoglobin level (choice B) is related to anemia and not directly indicative of TPN effectiveness. Albumin level (choice A) is a marker of nutritional status over a longer term and may not reflect immediate TPN effectiveness. White blood cell count (choice C) is related to infection or inflammation and is not a direct indicator of TPN effectiveness.

Correct Answer: B

Rationale: The correct answer is B: 'Insert a large-bore NG tube.' When performing a gastric lavage for a client with upper gastrointestinal bleeding, a large-bore NG tube is used to effectively remove gastric contents and blood. Option A is incorrect because the amount of solution to instill depends on the specific situation and should be guided by the healthcare provider's order. Option C is incorrect because using a cold irrigation solution can lead to hypothermia and is not recommended. Option D is incorrect as there is no need to instruct the client to lie on his right side specifically for gastric lavage.

Correct Answer: A

Rationale: The correct action for the nurse preparing to administer a controlled substance is to witness the waste of the controlled substance by another nurse. This practice is crucial to prevent misuse and ensure accurate documentation. Choice B is incorrect because disposing of the controlled substance by oneself without proper witnessing is not in accordance with safety protocols. Choice C is incorrect as leaving a controlled substance unattended in a client's room poses risks of diversion or unauthorized access. Choice D is incorrect because documenting the administration and signing off at the end of the shift is important but does not specifically address the issue of witnessing the waste of a controlled substance, which is a critical step in ensuring proper handling and accountability.

Correct Answer: A

Rationale: Clay-colored stools are a classic finding in a client with cirrhosis. Cirrhosis can lead to impaired bile flow, resulting in pale or clay-colored stools due to a lack of bilirubin in the stool. Hypertension, stridor, and elevated temperature are not typically associated with cirrhosis. Hypertension may occur in cirrhosis but is not a consistent finding, stridor is more commonly associated with upper airway obstruction, and elevated temperature may indicate an infection rather than a direct result of cirrhosis.
