Correct Answer: B

Rationale: Searching personal belongings is essential to ensure the safety of the client by preventing access to items that could be used for self-harm. While explaining the program's guidelines (Choice A) and initiating a psychosocial assessment (Choice C) are important aspects of care, the immediate concern in this situation is the safety of the client. Reviewing the healthcare provider's prescription (Choice D) is important for providing appropriate treatment but is not as urgent as ensuring the client's safety.

Correct Answer: C

Rationale: The correct action for the nurse to take first is to assess the client's oxygen saturation level. In a client with COPD and abnormal respiratory and heart rates, determining the oxygen saturation helps evaluate the adequacy of oxygen exchange and the severity of respiratory distress. Administering a bronchodilator (choice A) can be appropriate but assessing oxygen saturation takes priority. Encouraging deep breathing and coughing (choice B) may not address the immediate need for oxygenation assessment. Obtaining an arterial blood gas (choice D) is important but typically follows the initial assessment of oxygen saturation.

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: A

Rationale: The correct answer is A: 'It helps my body make red blood cells.' Erythropoietin is a medication that stimulates the production of red blood cells in the body. Clients with chronic renal failure often develop anemia due to decreased erythropoietin production by the kidneys. This medication helps address that issue by increasing red blood cell production. Choices B, C, and D are incorrect because erythropoietin does not prevent infections, help kidneys excrete excess fluid, or assist with breathing; its primary action is to boost red blood cell production.

Correct Answer: C

Rationale: Increased blood pressure is the desired effect of administering dopamine (Intropin) to treat hypotension. Dopamine acts by stimulating adrenergic receptors, leading to vasoconstriction and increased cardiac output. This results in an elevation of blood pressure. Choices A, B, and D are incorrect as they do not directly reflect the therapeutic action of dopamine in treating hypotension. Increased heart rate may indicate the body compensating for low blood pressure, increased urinary output is more related to kidney function, and increased respiratory rate is often seen in response to respiratory issues, not the action of dopamine on hypotension.
