1. What are the early signs of increased intracranial pressure (IICP)?

A. Restlessness, irritability, and confusion
B. Sudden onset of seizures
C. Decreased heart rate and pupillary response
D. Loss of consciousness

Correct answer: A

Rationale: The correct answer is A: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These signs indicate that the brain is starting to experience pressure, often due to conditions such as trauma, tumors, or hemorrhage. Sudden onset of seizures (choice B) is not typically an early sign of IICP but can occur later as the pressure increases. Decreased heart rate and pupillary response (choice C) are more indicative of late-stage IICP as the brainstem becomes compromised. Loss of consciousness (choice D) is a late sign of IICP when the pressure has significantly increased and is causing significant brain dysfunction.

2. 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.

3. What is the first medication to give for 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: Albuterol is the first-line medication for treating wheezing due to an allergic reaction. Albuterol is a short-acting beta-agonist that helps relieve bronchospasm quickly. Cromolyn is more commonly used for the prevention of asthma symptoms rather than for acute treatment. Methylprednisolone and aminophylline are not the first-line medications for acute wheezing due to an allergic reaction.

4. What is the priority intervention for a patient with unstable angina?

A. Administer nitroglycerin
B. Establish IV access
C. Auscultate heart sounds
D. Administer aspirin

Correct answer: A

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with unstable angina as it helps dilate blood vessels, improve blood flow to the heart, relieve chest pain, and prevent further cardiac damage. Establishing IV access (choice B) may be important but is not the priority over administering nitroglycerin in this scenario. Auscultating heart sounds (choice C) and administering aspirin (choice D) are also important aspects of managing unstable angina, but they are not the immediate priority intervention when a patient is experiencing chest pain.

5. What is the priority nursing action when a patient with chest pain presents with possible acute coronary syndrome?

A. Administer sublingual nitroglycerin
B. Obtain IV access
C. Check the patient's cardiac enzymes
D. Administer aspirin

Correct answer: A

Rationale: The priority nursing action when a patient with chest pain presents with possible acute coronary syndrome is to administer sublingual nitroglycerin. Sublingual nitroglycerin helps dilate blood vessels, reducing cardiac workload, and improving blood supply to the heart muscle, thus relieving pain and enhancing blood flow to the heart. While obtaining IV access is important for administering medications and fluids, it is not the priority over addressing pain and improving blood flow. Checking the patient's cardiac enzymes is crucial for diagnosis and ongoing management but not the immediate priority when the patient is in pain. Administering aspirin is also a vital intervention in acute coronary syndrome, but in this scenario, it is not the priority action compared to providing immediate pain relief and enhancing blood flow to the heart.
