Correct Answer: B

Rationale: When a client is prescribed alendronate (Fosamax), instructing them to avoid rapid movements after taking the medication is crucial to prevent esophageal irritation. Resting in bed after taking the medication for at least 30 minutes (choice A) is not necessary and can increase the risk of side effects. While taking the medication with water only (choice C) is generally recommended, the key instruction to prevent esophageal irritation is to avoid rapid movements. Allowing at least 1 hour between taking the medicine and other medications (choice D) is not specifically related to the administration of alendronate and is not the primary concern when giving instructions to the client.

Correct Answer: D

Rationale: After birth, newborns can lose weight due to meconium stool, loss of extracellular fluid, and the initiation of breastfeeding. This weight loss is a normal and expected physiological process, and infants can lose up to 10% of their birth weight during this period. There is no indication of dehydration (polyuria), hypoglycemia (lack of glucose), or allergy to the formula as reasons for weight loss in newborns. Therefore, answers A, B, and C are incorrect. Answer D provides the most accurate explanation for the observed weight loss in the newborn.

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: D

Rationale: A birth weight of 7 pounds typically triples by the age of 1 year, resulting in an expected weight of 21 pounds. This significant weight gain is a normal growth pattern for infants as they usually experience rapid growth in the first year of life. Choices A, B, and C are incorrect because they do not account for the usual growth rate of an infant in the first year. Infants commonly triple their birth weight by the age of 1, making 21 pounds the expected weight.

Correct Answer: B

Rationale: The appropriate action for the registered nurse in this scenario is to report the behavior to the charge nurse. This allows for proper investigation and intervention. Inappropriate actions include notifying the police directly without following the chain of command (Choice A), monitoring without immediate action (Choice C), and confronting the assistant without involving a superior (Choice D). By reporting to the charge nurse, the situation is escalated appropriately within the healthcare setting, ensuring the well-being and safety of the client.
