A client is receiving a low dose of dopamine (Intropin) IV for the treatment of hypotension. Which indicator reflects that the medication is having the desired effect?
- A. Increased heart rate
- B. Increased urinary output
- C. Increased blood pressure
- D. Increased respiratory rate
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.

The nurse preceptor is orienting a new graduate nurse to the critical care unit. The preceptor asks the new graduate to state symptoms that most likely indicate the beginning of a shock state in a critically ill client. What findings should the new graduate nurse identify?
- A. Tachycardia, mental status change, and low urine output
- B. Warm skin, hypertension, and constricted pupils
- C. Bradycardia, hypotension, and respiratory acidosis
- D. Mottled skin, tachypnea, and hyperactive bowel sounds
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.
The nurse is preparing to administer an IM dose of vitamin B1 (Thiamine) to a male client experiencing acute alcohol withdrawal and peripheral neuritis. The client belligerently states, 'What do you think you're doing?' How should the nurse respond?
- A. I cannot give you this medication until you calm down.
- B. This shot will help relieve the pain in your feet.
- C. Would you prefer to learn to administer your own shot?
- D. You will feel calmer and less jittery after this shot.
Correct Answer: B
Rationale: Choice B is the correct answer because it addresses the client's concern by explaining that the shot will help relieve the pain in his feet, which is a symptom of peripheral neuritis. This response shows empathy and provides the client with a clear benefit of receiving the medication. Choices A, C, and D do not directly address the client's immediate concern about the injection and its purpose, making them less suitable responses. Choice A focuses on the client's behavior rather than the therapeutic effect of the injection. Choice C shifts the responsibility to the client to administer the shot, which may not be appropriate in this situation. Choice D mentions feeling calmer and less jittery, which is not directly related to the client's current complaint of pain in the feet.
Which assessment finding should indicate to the nurse that a client with arterial hypertension is experiencing a cardiac complication?
- A. Complaints of an occipital headache
- B. A palpable dorsal pedis pulse bilaterally
- C. Complaints of shortness of breath on exertion
- D. A blood pressure of 160/90
Correct Answer: C
Rationale: The correct answer is C, complaints of shortness of breath on exertion. This symptom is indicative of heart failure, a common cardiac complication of arterial hypertension. Shortness of breath on exertion is often due to the heart's inability to pump effectively, leading to fluid buildup in the lungs. Choices A, B, and D are incorrect because complaints of an occipital headache, a palpable dorsal pedis pulse bilaterally, and a blood pressure of 160/90 do not specifically indicate a cardiac complication in a client with arterial hypertension.
The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who has a respiratory rate of 32 breaths/min and a heart rate of 110 beats/min. What action should the nurse take first?
- A. Administer a bronchodilator
- B. Encourage deep breathing and coughing
- C. Assess the client's oxygen saturation level
- D. Obtain an arterial blood gas
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.
The nurse is planning care for a client with a stage III pressure ulcer. Which intervention is most important for the nurse to include in the plan of care?
- A. Reposition the client every 2 hours
- B. Cleanse the ulcer with normal saline
- C. Apply a moisture-retentive dressing
- D. Measure the ulcer's depth and diameter
Correct Answer: D
Rationale: The correct answer is to measure the ulcer's depth and diameter. This intervention is crucial as it helps monitor healing progress and evaluate the effectiveness of the care plan. Measuring the ulcer provides valuable information about the wound's improvement or deterioration. Repositioning the client every 2 hours (Choice A) is important for preventing further skin breakdown but may not be the priority in this case. Cleansing the ulcer with normal saline (Choice B) is essential for wound care but not the most crucial intervention at this stage. Applying a moisture-retentive dressing (Choice C) can promote healing, but assessing the ulcer's dimensions is more critical for monitoring progress.
