Correct Answer: B

Rationale: Pale skin is a common sign of anemia due to reduced hemoglobin levels, leading to decreased oxygen delivery to tissues. This results in skin pallor. Choices A, C, and D are incorrect. Anemia typically causes fatigue and decreased energy levels (not increased), low blood pressure (not elevated), and tachycardia (increased heart rate) to compensate for the decreased oxygen-carrying capacity of the blood.

Correct Answer: C

Rationale: The correct answer is C. School-age children (6-12 years) are in Erikson's stage of industry vs. inferiority. During this stage, they strive to develop a sense of industry through learning and socialization. They seek to excel in various areas, such as schoolwork or activities, and look for approval from peers and adults. Choices A, B, and D are incorrect because personalizing values and beliefs, developing personal identity influenced by family expectations, and feeling guilty for inability to accomplish tasks are not typical behavioral findings for a school-age child in the context of psychosocial development.

Correct Answer: B

Rationale: The correct answer is to take metformin with food. This is important to minimize gastrointestinal side effects and improve absorption. Choice A is incorrect as metformin is not typically associated with weight gain. Choice C is wrong as metformin is not an insulin but a medication that helps control blood sugar levels. Choice D is also incorrect as metformin is not known to cause hyperglycemia.

Correct Answer: A

Rationale: Corrected Rationale: The nurse should encourage the client to use the PCA pump before activities like dressing changes, which are likely to cause pain, to ensure effective pain management. Monitoring the client's respiratory status (Choice B) is important but not the priority in this scenario. Providing oxygen therapy (Choice C) is not a routine intervention for all clients on PCA unless specifically indicated. Ensuring the PCA pump is functioning properly (Choice D) is essential, but encouraging the client to use the PCA before painful activities takes precedence to manage pain effectively.

Correct Answer: B

Rationale: The correct answer is B: 'Sit upright for at least 30 minutes after taking it.' Alendronate can cause esophageal irritation and to reduce the risk of this side effect, clients should be instructed to sit upright for at least 30 minutes after administration. Choice A is incorrect as alendronate should be taken on an empty stomach, usually in the morning, at least 30 minutes before the first food, beverage, or medication of the day. Choice C is incorrect because alendronate should not be taken at bedtime, as the client should remain upright for at least 30 minutes after taking it. Choice D is incorrect as antacids can interfere with the absorption of alendronate, so they should not be taken together.
