1. What should the nurse monitor for in a patient with hypokalemia?

A. Monitor for muscle weakness
B. Check deep tendon reflexes (DTRs)
C. Monitor for seizures
D. Monitor for bradycardia

Correct answer: A

Rationale: The correct answer is to monitor for muscle weakness in a patient with hypokalemia. Hypokalemia, which is low potassium levels, can lead to muscle weakness due to its effects on neuromuscular function. Checking deep tendon reflexes (Choice B) is not typically associated with hypokalemia. Seizures (Choice C) are more commonly associated with low calcium levels rather than low potassium levels. Bradycardia (Choice D) is a symptom of hyperkalemia (high potassium levels) rather than hypokalemia.

2. What is a characteristic sign of hypokalemia on an ECG?

A. Flattened T waves
B. ST elevation
C. Prominent U waves
D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic sign of hypokalemia on an ECG. When potassium levels are low, it can lead to changes in the ECG, such as T wave flattening. This alteration is important to recognize as it indicates potential electrolyte imbalances. ST elevation (Choice B) is not typically associated with hypokalemia but can be seen in conditions like myocardial infarction. Prominent U waves (Choice C) are associated with hypokalemia, but flattened T waves are more specific. Widened QRS complex (Choice D) is not a typical ECG finding in hypokalemia but can be seen in conditions like hyperkalemia.

3. A nurse is caring for a client who has a traumatic brain injury. Which of the following findings should indicate to the nurse the need for immediate intervention?

A. Axillary temperature 37.2°C (99°F)
B. Apical pulse 100/min
C. Respiratory rate 30/min
D. Blood pressure 140/84 mm Hg

Correct answer: C

Rationale: The correct answer is C. The nurse should prioritize airway and breathing in a client with a traumatic brain injury. An increased respiratory rate may indicate CO2 retention, which could lead to increased intracranial pressure. Choice A, axillary temperature 37.2°C (99°F), is within normal range and does not indicate an immediate need for intervention. Choice B, apical pulse 100/min, is slightly elevated but not as critical as respiratory distress in this scenario. Choice D, blood pressure 140/84 mm Hg, is also within normal limits and does not require immediate intervention compared to the respiratory rate.

4. What should be monitored for in a patient with compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Localized redness and swelling
C. Fever and infection
D. Muscle weakness and fatigue

Correct answer: A

Rationale: Correct Answer: A. Unrelieved pain, pallor, and pulselessness are classic signs of compartment syndrome that indicate inadequate blood flow to the affected area. These symptoms are crucial to monitor as they signify a medical emergency requiring immediate intervention. Choices B, C, and D are incorrect because they do not align with the typical manifestations of compartment syndrome. Localized redness and swelling may be present but are not the primary indicators. Fever and infection are also not specific to compartment syndrome, and muscle weakness and fatigue are not typically prominent symptoms of this condition.

5. What is the initial action for treating chest pain in acute coronary syndrome?

A. Administer sublingual nitroglycerin
B. Administer aspirin
C. Check cardiac enzymes
D. Obtain IV access

Correct answer: A

Rationale: The correct initial action for treating chest pain in acute coronary syndrome is to administer sublingual nitroglycerin. Nitroglycerin helps dilate blood vessels, reducing the workload on the heart and improving blood flow to the heart muscle. Administering aspirin can also be beneficial, but the priority is to address chest pain promptly. Checking cardiac enzymes and obtaining IV access are important steps but are not the initial actions needed to alleviate chest pain in acute coronary syndrome.
