Correct Answer: B

Rationale: The correct answer is B: Decreased cardiac output. Fatigue in heart failure is primarily due to decreased cardiac output, leading to reduced oxygen and nutrient delivery to tissues, causing fatigue. Dyspnea (A) is shortness of breath, not fatigue. Dry cough (C) is more associated with conditions like pulmonary issues, not fatigue. Orthopnea (D) is difficulty breathing while lying down, not specifically related to fatigue. Hence, decreased cardiac output is the most likely cause of fatigue in this patient.

Correct Answer: A

Rationale: The correct answer is A because during the first phase of the nursing process (assessment), the nurse collects a comprehensive database of information about the patient's health status and needs. This data forms the foundation for identifying nursing diagnoses, planning interventions, and evaluating outcomes. Choices B, C, and D involve actions that occur in the subsequent phases of the nursing process (diagnosis, planning, and evaluation), not in the initial assessment phase. Therefore, A is the correct choice for the first phase.

Correct Answer: D

Rationale: The correct answer is D. First, the nurse should put the implant back in place using forceps and a shield for self-protection. This is important to limit the exposure to radiation for both the client and the nurse. Second, the nurse should call for help to ensure proper handling and further assistance. Standing away from the implant (choice A) does not address the immediate need to secure the implant. Picking up the implant with long-handled forceps and placing it in a lead-lined container (choice B) should only be done by trained personnel to prevent further exposure. Leaving the room and notifying the radiation therapy department immediately (choice C) delays the immediate action needed to prevent unnecessary radiation exposure.

Correct Answer: C

Rationale: Correct Answer: C - Tracheostomy set Rationale: 1. Immediate airway management: After thyroidectomy, there is a risk of airway compromise due to swelling or bleeding. Tracheostomy set ensures immediate access to secure the airway. 2. Emergency intervention: In case of respiratory distress or airway obstruction post-surgery, a tracheostomy set allows for prompt and effective intervention. 3. Patient safety and priority: Ensuring airway patency is crucial for the client's survival and takes precedence over other equipment. Summary of other choices: A: Indwelling urinary catheter kit - Not directly related to post-thyroidectomy care. B: Cardiac monitor - Important but secondary to airway management in this situation. D: Humidifier - Not essential for immediate post-thyroidectomy care.

Correct Answer: D

Rationale: The correct answer is D: 60 seconds. This is because the area must be cleaned for at least 60 seconds to effectively disinfect the skin and reduce the risk of infection during venipuncture. Cleaning for shorter durations (5, 10, or 30 seconds) may not be sufficient to achieve proper disinfection. Thoroughly cleaning the area for a full minute ensures that the alcohol has enough time to kill bacteria and pathogens on the skin, making it safer for the venipuncture procedure. Shorter cleaning times may leave pathogens behind, increasing the risk of contamination and infection.
