Correct Answer: A

Rationale: Bilirubin is excreted through the kidneys, therefore increasing fluid intake can help facilitate its elimination. Maintaining the infant's body temperature is important for overall health but does not directly assist in eliminating bilirubin, making choice B incorrect. Choices C and D are irrelevant to bilirubin elimination in this scenario and do not address the specific issue of physiologic jaundice.

Correct Answer: A

Rationale: The correct answer is that amphetamines increase energy by increasing dopamine levels at neural synapses. Amphetamines cause the release of norepinephrine and dopamine from storage vesicles into the synapse, leading to increased stimulation. It is important to note that clear patterns of tolerance and withdrawal have not been described with amphetamines. Choice B is incorrect as prolonged or excessive use of amphetamines can lead to psychosis, indicating a potential for addiction. Choice C is incorrect as the duration of the effects of amphetamines is typically longer than 2-4 hours. Choice D is incorrect as addiction to amphetamines is not rare; in fact, drug cravings are common and can lead to relapse, indicating a significant risk of addiction.

Correct Answer: B

Rationale: Montgomery straps are used to secure dressings that require frequent changes due to the large amount of drainage usually present after a cholecystectomy. They are also beneficial for clients allergic to various types of tape. Answer A is incorrect as the client is not at higher risk of evisceration. Answer C is incorrect because Montgomery straps are not used to support drains. Answer D is incorrect as sutures or clips are typically used to secure the incision after gallbladder surgery, not Montgomery straps.

Correct Answer: B

Rationale: The correct answer is 'Mania.' A client with a serum sodium level of 170 meq/L has hypernatremia, which can lead to manic behavior. Hypernatremia is associated with irritability, restlessness, confusion, and in severe cases, manic symptoms. Choices A, C, and D (Anger, Depression, Psychosis) are not typically associated with hypernatremia and are, therefore, incorrect in this context.

Correct Answer: B

Rationale: Child abuse is often associated with lower socioeconomic status and single-parent households due to increased stress and fewer support systems. Choice A is correct as single-parent households can face more challenges leading to a higher risk of child abuse. Choice B is the correct answer as it aligns with the risk factors associated with child abuse. Choice C is incorrect because there is no direct correlation between stricter child-rearing practices and child abuse rates. Choice D is incorrect because attributing child abuse to a higher occurrence of rage in African Americans is a stereotype and lacks evidence.
