How should a healthcare professional monitor a patient receiving IV potassium?

Correct Answer: C

Rationale: When a patient is receiving IV potassium, it is crucial to monitor the IV site. Potassium can be irritating to the veins and may cause phlebitis or infiltration. Monitoring the IV site allows early detection of any potential complications. Checking urine output (Choice A) is important to assess kidney function but is not directly related to monitoring IV potassium. Blood pressure (Choice B) and respiratory rate (Choice D) are essential vital signs to monitor in general patient care but are not specific to monitoring IV potassium administration.

Correct Answer: D

Rationale: Giving a bowel prep solution is essential to clean out the colon thoroughly before a colonoscopy. This process is crucial as it helps to achieve a clear view of the colon during the procedure. Providing clear instructions on diet (Choice A) and ensuring the patient has an empty stomach (Choice C) are important steps in the preparation process but may not be sufficient on their own to adequately cleanse the colon. Explaining the procedure in detail (Choice B) is helpful for patient education but does not directly contribute to the physical preparation required for a successful colonoscopy.

Correct Answer: C

Rationale: Suctioning the tracheostomy regularly is crucial in caring for a patient with a tracheostomy as it helps keep the airway clear of secretions, preventing blockages and potential complications. Cleaning the tracheostomy site daily is important for hygiene but not as critical as regular suctioning. Changing the tracheostomy ties daily may not be necessary unless soiled or loose. Providing humidified oxygen may be part of the care plan but is not as directly related to maintaining the tracheostomy patency as suctioning.

Correct Answer: A

Rationale: The correct answer is to administer calcium gluconate. In hyperkalemia, the priority is to protect the heart from potential complications like arrhythmias. Calcium gluconate is the first-line treatment as it stabilizes the cardiac cell membrane. Insulin (Choice B) and sodium bicarbonate (Choice C) can be used in conjunction with other treatments to shift potassium into cells, but calcium gluconate is the priority. Administering a diuretic (Choice D) is not the primary intervention for hyperkalemia and can even worsen the condition by reducing potassium excretion.

Correct Answer: C

Rationale: The correct answer is C, respiratory depression. When a patient is receiving morphine, respiratory depression is the most concerning side effect because it can lead to serious complications, including respiratory arrest and even death. Monitoring the patient's respiratory status is crucial to ensure early detection of any signs of respiratory depression. Choices A, B, and D are incorrect because although hypotension, bradycardia, and hypertension can occur as side effects of morphine, they are not as immediately life-threatening as respiratory depression in this context.
