The client who does not respond adequately to fluid replacement has an order for an I.V. infusion of dopamine hydrochloride at 5 µg/kg/minute. To determine that the drug is having the desired effect, the nurse should assess the client for:
- A. Increased renal and mesenteric blood flow.
- B. Increased cardiac output.
- C. Vasoconstriction.
- D. Reduced preload and afterload.
Correct Answer: B
Rationale: Dopamine at 5 µg/kg/minute primarily increases cardiac output by enhancing myocardial contractility and heart rate, improving perfusion in shock. Renal/mesenteric flow occurs at lower doses, vasoconstriction at higher doses, and preload/afterload reduction is not a primary effect.

The nurse notices that a client with Parkinson's disease is coughing frequently when eating. Which one of the following interventions should the nurse consider?

- B. Tell the client to place the chin firmly against the chest when eating.
- C. Thicken all liquids before offering to the client.
- D. Place the client on a clear liquid diet.
Correct Answer: C
Rationale: Thickening liquids reduces aspiration risk in Parkinson's patients with dysphagia, as coughing indicates swallowing difficulty. Hyperextending the neck or a clear liquid diet increases aspiration risk, and chin tuck is less universally effective.
