The nurse is assessing a client with a history of heart failure who reports new-onset dyspnea and fatigue. Which finding requires the most immediate intervention?

Crackles in bilateral lower lobes.

Heart rate of 92 beats/minute.

Blood pressure of 138/86 mm Hg.

Peripheral edema 1+ in ankles.

Answer and Explanation

The Correct Answer is A

Choice A reason: Crackles in bilateral lower lobes indicate pulmonary edema in heart failure, where reduced cardiac output causes fluid backup into alveoli, impairing gas exchange and causing dyspnea. This life-threatening emergency requires immediate diuretics or oxygen to reduce preload, preventing respiratory failure or hypoxia, prioritizing intervention.

Choice B reason: A heart rate of 92 beats/minute is normal and not urgent in heart failure, where dyspnea and fatigue suggest fluid overload. Crackles indicate pulmonary edema, a critical issue compromising oxygenation, necessitating immediate action to restore respiratory function, making heart rate less concerning.

Choice C reason: Blood pressure of 138/86 mm Hg is mildly elevated but not critical in heart failure. Crackles signal pulmonary edema, where fluid in alveoli impairs gas exchange, risking hypoxia. This requires urgent intervention like furosemide, as respiratory compromise is more immediate than managing stable blood pressure.

Choice D reason: Peripheral edema 1+ indicates fluid retention in heart failure but is less urgent than crackles, which signify pulmonary edema. Alveolar fluid causes dyspnea and hypoxia, requiring immediate diuretics. Edema is chronic, making respiratory assessment and intervention the priority to prevent acute respiratory failure.

Correct Answer is B

Explanation

Choice A reason: Exercise lowers blood glucose in type 2 diabetes by enhancing insulin sensitivity and glucose uptake via GLUT4 transporters in muscles. This statement is incorrect, as physical activity is vital for glycemic control, reducing hyperglycemia and cardiovascular risks. Proper understanding involves recognizing exercise’s role in metabolic management, not denying its impact.

Choice B reason: Following a tailored meal plan and avoiding high-fat diets is correct, as it regulates blood glucose and lipids in type 2 diabetes. Balanced carbohydrates and low saturated fats prevent insulin resistance and atherosclerosis. This reflects understanding of dietary management’s role in glycemic control, reducing complications like neuropathy or cardiovascular disease.

Choice C reason: Soaking feet in hot water is dangerous in diabetes due to neuropathy, which reduces sensation and increases burn risk. Hot water also dries skin, raising infection risk. Proper foot care involves daily inspection and avoiding extreme temperatures, making this statement incorrect and harmful for effective diabetes management.

Choice D reason: Covering wounds with antibiotic ointment without medical evaluation is risky, as diabetes impairs wound healing due to hyperglycemia and immune dysfunction. Proper care involves cleaning, monitoring, and consulting providers to prevent infections. This statement shows incomplete understanding, as it overlooks the need for professional wound management.

A. Clear breath sounds on auscultation. B. Increased respiratory rate. C. Decreased oxygen saturation. D. Presence of wheezing.

Correct Answer is A

Explanation

Choice A reason: Clear breath sounds indicate effective suctioning, as it removes secretions obstructing the airway, improving ventilation. This aligns with the goal of endotracheal suctioning to maintain airway patency, ensuring adequate oxygenation and reducing infection risk, per critical care and respiratory management protocols in nursing practice.

Choice B reason: Increased respiratory rate suggests respiratory distress, indicating ineffective suctioning. Clear breath sounds confirm secretion removal, ensuring airway patency. A rising rate may reflect persistent obstruction or hypoxia, requiring further intervention, per respiratory assessment and critical care standards for endotracheal tube management in nursing.

Choice C reason: Decreased oxygen saturation indicates ineffective suctioning, as secretions likely remain, impairing oxygenation. Clear breath sounds confirm airway clearance, improving gas exchange. Low saturation requires immediate reassessment, per oxygenation monitoring and critical care protocols for clients with endotracheal tubes in nursing practice.

Choice D reason: Presence of wheezing suggests airway narrowing or persistent secretions, indicating ineffective suctioning. Clear breath sounds demonstrate successful secretion removal, ensuring unobstructed airflow. Wheezing requires further intervention, per respiratory assessment and airway management standards in critical care nursing for intubated clients.
