How should a healthcare professional prepare a patient for a colonoscopy?

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: 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.

Correct Answer: A

Rationale: The correct answer is to check oxygen saturation. This is because checking oxygen saturation provides a direct measure of how well the patient is oxygenating post-surgery. It helps healthcare providers assess if the patient is receiving enough oxygen to meet their body's needs. Auscultating lung sounds (choice B) is important to assess respiratory function but may not provide an immediate indication of oxygenation status. Checking for abnormal breath sounds (choice C) is relevant but does not directly assess oxygenation levels. Checking skin color (choice D) can provide some information about oxygenation, but it is not as precise or direct as measuring oxygen saturation.

Correct Answer: A

Rationale: The correct answer is A: "Respect the patient's decision and notify the provider." When a patient refuses a blood transfusion due to religious beliefs, it is essential to respect their autonomy and religious beliefs. Attempting to persuade the patient (Choice B) goes against the principle of respect for autonomy and can lead to ethical dilemmas. Documenting the refusal and notifying the healthcare provider (Choice C) is important for legal and ethical purposes but should be preceded by respecting the patient's decision. Providing education on the benefits of blood transfusion (Choice D) may be appropriate in other situations but is not indicated when a patient refuses based on religious beliefs.
