1. What ECG changes should be monitored in a patient with hypokalemia?

A. Flattened T waves and prominent U waves
B. Elevated ST segments and wide QRS complexes
C. Tall T waves and flattened QRS complexes
D. Widened QRS complexes and decreased P wave amplitude

Correct answer: A

Rationale: The correct answer is A: Flattened T waves and prominent U waves. In hypokalemia, there is a decrease in potassium levels, which can lead to ECG changes such as flattened T waves and prominent U waves. These changes are classic findings associated with hypokalemia. Choices B (Elevated ST segments and wide QRS complexes), C (Tall T waves and flattened QRS complexes), and D (Widened QRS complexes and decreased P wave amplitude) are all incorrect. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia. Tall T waves and flattened QRS complexes, as well as widened QRS complexes and decreased P wave amplitude, do not represent the typical ECG changes seen in hypokalemia.

2. A nurse is caring for a client who has increased intracranial pressure (ICP). Which of the following interventions should the nurse implement?

A. Place several pillows behind the client's head
B. Place the client in a Sim's position
C. Keep the client's neck in a midline position
D. Maintain flexion of the client's hips at a 90° angle

Correct answer: C

Rationale: Keeping the client's neck in a midline position is crucial for managing increased intracranial pressure. This position helps optimize blood flow and minimizes the risk of further increasing ICP. Placing several pillows behind the client's head (Choice A) may inadvertently elevate the head, potentially worsening ICP. Placing the client in a Sim's position (Choice B) or maintaining flexion of the client's hips at a 90° angle (Choice D) are not directly related to managing increased ICP.

3. What should the healthcare provider do if a patient presents with chest pain and possible acute coronary syndrome?

A. Administer sublingual nitroglycerin
B. Administer aspirin
C. Obtain cardiac enzymes
D. Get IV access and auscultate heart sounds

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the priority action in the treatment of chest pain in acute coronary syndrome. Nitroglycerin helps dilate blood vessels, improving blood flow to the heart and relieving chest pain. Aspirin can also be given to reduce clot formation, but nitroglycerin takes precedence in providing immediate relief. Obtaining cardiac enzymes and assessing heart sounds are important steps in the diagnostic process but do not address the immediate need to relieve chest pain and prevent cardiac tissue damage. Therefore, administering sublingual nitroglycerin is the most appropriate initial intervention for a patient presenting with chest pain and possible acute coronary syndrome.

4. What is the first medication to give to a patient experiencing wheezing due to an allergic reaction?

A. Albuterol via nebulizer
B. Cromolyn 20 mg via nebulizer
C. Methylprednisolone 100 mg IV
D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol via nebulizer. Albuterol is the first-line treatment for wheezing caused by an allergic reaction due to its rapid action in opening airways. Cromolyn (Choice B) is used for prevention rather than acute treatment. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in allergic reactions.

5. What dietary recommendations should be given to a patient with GERD?

A. Avoid mint and spicy foods
B. Eat large meals before bed
C. Increase fluid intake during meals
D. Drink milk as a snack

Correct answer: A

Rationale: The correct dietary recommendation for a patient with GERD is to avoid mint and spicy foods. These foods can trigger symptoms of GERD and lead to acid reflux. Choice B is incorrect because eating large meals before bed can exacerbate GERD symptoms by increasing the likelihood of acid reflux during sleep. Choice C is incorrect as increasing fluid intake during meals can worsen GERD symptoms by distending the stomach, leading to increased pressure on the lower esophageal sphincter. Choice D is also incorrect because while milk may provide temporary relief for some individuals, it is not a recommended long-term solution for managing GERD.
