Correct Answer: D

Rationale: A pulmonary embolism can manifest with sudden shortness of breath, chest pain, and coughing up blood. These symptoms are classic presentations of a pulmonary embolism due to the blockage of blood flow to the lungs. Therefore, the correct answer is 'All of the above.' Each symptom alone can be seen in various other conditions, but when occurring together, they strongly suggest a pulmonary embolism. Sudden shortness of breath is due to decreased oxygenation, chest pain can result from the strain on the heart, and coughing with blood may indicate damage to the lung tissue. Choosing any single symptom would not encompass the full range of presentations seen in a pulmonary embolism.

Correct Answer: A

Rationale: Corrected Rationale: Regular monitoring for infection and dressing changes are essential aspects of caring for a patient with a central venous catheter. Infections are a significant risk with these catheters, so vigilant monitoring and timely dressing changes help prevent complications. Choice B is important too, but ensuring catheter patency and flushing are more focused on maintaining the functionality of the catheter rather than infection prevention. Choice C is also important for patient education, but the immediate concern for a healthcare professional is monitoring and preventing infections related to the catheter. Choice D is not directly related to the care of a central venous catheter.

Correct Answer: A

Rationale: The Z-track method should be used to administer IM injections in obese clients to prevent medication from leaking into subcutaneous tissue. Using a longer needle (1.5 inches) ensures that the medication reaches the muscle mass adequately. Choice C is incorrect because the deltoid muscle is not ideal for IM injections in obese clients due to inadequate muscle mass. Administering the injection at a 90° angle (perpendicular to the skin) is recommended for IM injections to ensure proper delivery into the muscle.

Correct Answer: A

Rationale: The correct instruction the nurse should include is to 'Use pursed-lip breathing during physical activity.' Pursed-lip breathing is a technique that helps improve breathing efficiency in individuals with COPD by preventing airway collapse and allowing for better air exchange. Choice B is incorrect because breathing deeply and quickly can lead to hyperventilation and worsen symptoms in COPD patients. Choice C is incorrect because the incentive spirometer is a device used to encourage deep breathing and improve lung function, so it should not be avoided. Choice D is incorrect because physical activity is important for maintaining overall health and should be encouraged in a controlled and appropriate manner for individuals with COPD.

Correct Answer: D

Rationale: Managing a patient with sepsis requires a multi-faceted approach. Administering IV antibiotics is crucial to combat the underlying infection. Monitoring vital signs such as heart rate, blood pressure, respiratory rate, and temperature helps assess the patient's response to treatment and identify any deterioration. Administering fluids is essential to maintain adequate blood pressure and organ perfusion. Therefore, all the options are integral components of sepsis management, making 'All of the above' the correct answer. Choices A, B, and C are all essential in the comprehensive care of a patient with sepsis. Omitting any of these aspects can lead to suboptimal outcomes, as each plays a critical role in addressing different aspects of sepsis management.
