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

A. Restlessness, confusion, irritability
B. Severe nausea and vomiting
C. Elevated blood pressure and bradycardia
D. Decreased heart rate and altered pupil response

Correct answer: A

Rationale: The correct manifestations of increased intracranial pressure (IICP) include restlessness, confusion, and irritability. These symptoms are a result of the brain being under pressure inside the skull. Severe nausea and vomiting (Choice B) are more commonly associated with increased intracranial pressure in children. Elevated blood pressure and bradycardia (Choice C) are not typical manifestations of increased intracranial pressure; instead, hypertension and bradycardia may be seen in Cushing's reflex, which is a late sign of increased IICP. Decreased heart rate and altered pupil response (Choice D) are also not primary manifestations of increased intracranial pressure, although altered pupil response, like a non-reactive or dilated pupil, can be seen in some cases.

2. What is the first-line treatment for wheezing due to an allergic reaction?

A. Albuterol via nebulizer
B. Cromolyn 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 because it acts quickly to open the airways by relaxing the muscles in the air passages. Cromolyn (Choice B) is used for asthma prevention rather than acute wheezing. Methylprednisolone (Choice C) and Aminophylline (Choice D) are not the first-line treatments for acute wheezing in the setting of an allergic reaction.

3. How does hyponatremia place the patient at risk?

A. Seizures
B. Fatigue
C. Cardiac dysrhythmias
D. Muscle weakness

Correct answer: C

Rationale: Hyponatremia places the patient at risk for cardiac dysrhythmias. While hyponatremia can lead to seizures due to cerebral edema caused by fluid imbalance, the most immediate and life-threatening risk is cardiac dysrhythmias. Low sodium levels can disrupt the heart's electrical activity, potentially leading to fatal arrhythmias. Although fatigue and muscle weakness are symptoms of hyponatremia, cardiac dysrhythmias pose the most critical concern as they can have severe consequences.

4. What are the early symptoms of compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Localized redness and swelling
C. Fever and swelling
D. Numbness and tingling

Correct answer: A

Rationale: The correct answer is A: 'Unrelieved pain, pallor, and pulselessness.' Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to reduced blood flow and potential tissue damage. Early symptoms include unrelieved pain (out of proportion to the injury), pallor (pale skin color), and pulselessness (decreased or absent pulses). Choices B, C, and D are incorrect as they do not represent the classic early symptoms of compartment syndrome.

5. What lab value should be prioritized in a patient with HIV?

A. CD4 T-cell count below 180 cells/mm3
B. White blood cell count
C. Serum albumin levels
D. Hemoglobin levels

Correct answer: A

Rationale: The correct answer is A: CD4 T-cell count below 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV as it indicates the level of immunocompromise. A count below 180 cells/mm3 signifies severe immunocompromise and an increased risk of opportunistic infections. Choices B, C, and D are not the priority lab values in HIV management. While white blood cell count, serum albumin levels, and hemoglobin levels are important, they do not directly reflect the immune status and progression of HIV as the CD4 T-cell count does.
