Correct Answer: A

Rationale: The primary concern when administering IV fluids to a client with a history of congestive heart failure (CHF) is monitoring for signs of fluid overload. Clients with CHF are particularly vulnerable to fluid overload, which can exacerbate their condition. Signs of fluid overload include edema and difficulty breathing. Therefore, the nurse must closely monitor these signs to prevent worsening of the client's condition. Choices B, C, and D are incorrect because while ensuring hydration, preventing electrolyte imbalances, and maintaining the prescribed rate of fluid administration are important, they are secondary concerns compared to the critical task of monitoring for fluid overload in a client with CHF.

Correct Answer: C

Rationale: The correct answer is C, Partial thromboplastin time (PTT). PTT is monitored to assess the therapeutic effect of heparin therapy. It helps ensure that the heparin levels are within the desired range to prevent either clotting or excessive bleeding. Platelet count (A) is important but does not directly assess heparin's therapeutic effect. Prothrombin time (PT) (B) and International normalized ratio (INR) (D) are used to monitor patients on warfarin, not heparin therapy.

Correct Answer: D

Rationale: The correct answer is 'D - All of the Above.' The PN should first don procedure gloves to maintain aseptic technique, then remove the dressing to assess the wound, and finally apply prescribed medications to the wound. This sequence ensures that non-sterile tasks like donning gloves are done before sterile tasks like applying medications, reducing the risk of wound contamination. Choices A, B, and C are all essential steps in providing effective wound care.

Correct Answer: C

Rationale: When caring for a patient with a newly inserted tracheostomy, the priority is to monitor for signs of infection and ensure a patent airway. This is crucial to prevent complications such as airway obstruction or infection. While keeping the tracheostomy tube clean and dry is important for overall care, it is not the highest priority when compared to ensuring a patent airway. Providing regular oral hygiene is essential for the patient's comfort but takes a secondary role to maintaining airway patency. Encouraging the patient to cough and deep breathe may be beneficial but is not as critical as monitoring for infection and keeping the airway clear.
