Correct Answer: B

Rationale: The client should be instructed to call when contractions are 5 minutes apart for an hour to ensure she is in active labor before going to the hospital.

Correct Answer: A

Rationale: Administering an antiemetic before meals is a crucial intervention to manage chemotherapy-induced nausea. Antiemetics are medications specifically designed to prevent or relieve nausea and vomiting. By administering the antiemetic before meals, the nurse can help prevent the onset of nausea, allowing the client to eat more comfortably. Providing frequent mouth care (Choice B) is important for maintaining oral hygiene but does not directly address nausea. Encouraging small, frequent meals (Choice C) and offering clear liquids (Choice D) are generally recommended for clients experiencing nausea, but administering an antiemetic is a more targeted approach to specifically address and manage the symptom.

Correct Answer: C

Rationale: The correct action for the nurse to take when a client on ciprofloxacin reports loss of appetite and a metallic taste in the mouth is to notify the healthcare provider of the client's symptoms. These symptoms could indicate a need for a change in medication or additional treatment, which the healthcare provider would need to assess. Instructing the client to take ciprofloxacin with food (choice B) may help with gastrointestinal upset but will not address the reported symptoms. Reassuring the client (choice A) is important for providing emotional support but does not address the need for further evaluation. Encouraging increased fluid intake (choice D) is generally beneficial but may not directly address the specific side effects reported.

Correct Answer: D

Rationale: Imbalanced nutrition is the most critical nursing diagnosis to address in this scenario. The patient's significant weight loss and neglect of basic needs, such as eating and personal hygiene, indicate a severe imbalance in nutrition. Addressing this issue is crucial to prevent further health deterioration. Self-care deficit, disturbed sleep pattern, and disturbed thought processes are important but secondary concerns compared to the immediate risk posed by imbalanced nutrition. While self-care deficit and disturbed sleep pattern are valid concerns, the patient's weight loss and neglect of basic needs take precedence. Disturbed thought processes are also significant but addressing the imbalanced nutrition is more urgent in this context.

Correct Answer: A

Rationale: The correct answer is A: Tachycardia, mental status change, and low urine output are early signs of shock. Tachycardia is the body's compensatory mechanism to maintain perfusion, mental status changes can indicate decreased cerebral perfusion, and low urine output reflects poor renal perfusion. Choices B, C, and D are incorrect. Warm skin, hypertension, and constricted pupils are not typical findings in the early stages of shock. Bradycardia, hypotension, and respiratory acidosis are more indicative of late-stage shock. Mottled skin, tachypnea, and hyperactive bowel sounds can be seen in various conditions but are not specific early signs of shock.
