Correct Answer: C

Rationale: The correct action for a nurse caring for a client with thrombocytopenia is to provide the client with a stool softener. Thrombocytopenia is a condition characterized by low platelet count, which can lead to bleeding problems. Providing a stool softener helps prevent constipation, which in turn prevents straining during bowel movements, reducing the risk of bleeding. Encouraging the client to floss daily (Choice A) is not directly related to thrombocytopenia. Removing fresh flowers from the client's room (Choice B) is more related to infection control rather than managing thrombocytopenia. Avoiding serving raw vegetables (Choice D) is not directly linked to managing thrombocytopenia.

Correct Answer: C

Rationale: The correct answer is C because using a mechanical lift is an ergonomic practice that ensures safe body mechanics and prevents injuries. Choice A is incorrect as standing with feet together when lifting a client does not promote proper body mechanics. Choice B is incorrect as raising the client's head of bed before pulling the client up is not directly related to ergonomic principles. Choice D is incorrect as placing a gait belt around the client's upper chest is a safety measure for assisting with standing but does not address ergonomic principles.

Correct Answer: C

Rationale: The correct answer is C: Penicillin allergy. Penicillin allergy is a contraindication for ceftriaxone because both medications are beta-lactam antibiotics. Seizure disorder (choice A), hypertension (choice B), and hyperlipidemia (choice D) are not contraindications for ceftriaxone and do not directly affect the use of this antibiotic.

Correct Answer: B

Rationale: The correct action for the nurse to take when caring for a client with alcohol use disorder experiencing withdrawal is to administer diazepam. Diazepam is a benzodiazepine commonly used to manage withdrawal symptoms in these clients by reducing anxiety, tremors, and the risk of seizures. Administering naloxone (Choice A) is used for opioid overdose, not alcohol withdrawal. Encouraging oral fluid intake (Choice C) is generally beneficial but not a specific intervention for alcohol withdrawal. Administering magnesium sulfate (Choice D) is not indicated for alcohol withdrawal but may be used for other conditions like preeclampsia or eclampsia.

Correct Answer: B

Rationale: A weight loss of 1.1 kg (2.5 lb) in 24 hours may indicate dehydration or fluid imbalance, which should be reported. This rapid weight loss could be a sign of excessive diuresis, potentially leading to hypovolemia or electrolyte imbalances. Monitoring weight changes is crucial in clients with heart failure receiving diuretics. The other findings are within normal ranges and expected in a client receiving furosemide for heart failure. A heart rate of 80/min, a potassium level of 3.8 mEq/L, and a urine output of 60 mL/hr are generally acceptable in this scenario.
