Question:

A 77-year-old woman reports explosive diarrhea for 48 hours. She is extremely lethargic. Mucous membranes are dry and sticky, and the urine is dark amber with a specific gravity of 1.035. Vital signs are temperature 38.2° C orally; heart rate 130 beats/min and regular; respiratory rate 26 breaths/min and regular; and blood pressure 90/74 mm Hg. Which of the following is of the most immediate concern?

• Infection
• Hypovolemia
• Nutrition
• Skin breakdown

Answer:

• Hypovolemia

Hypovolemia, especially in an older adult, is the most life threatening

Question:

What is the priority of management in respiratory acidosis?

• Improve alveolar ventilation by treating the cause of hypoventilation.
• Buffer the acid with sodium bicarbonate.
• Improve oxygenation by administering oxygen.
• Decrease anxiety to increase PaCO2 level.

Answer:

• Improve alveolar ventilation by treating the cause of hypoventilation.

Question:

Which of the following describes the pulse pressure of a patient with aortic regurgitation?

• 30 to 40 mm Hg
• Less than 30 mm Hg
• More than 40 mm Hg
• Varies with phase of respiratory cycle

Answer:

• More than 40 mm Hg

Aortic regurgitation causes a wide pulse pressure and water-hammer pulse, which is a rapid upstroke and downstroke and shortened peak. 2 / 4

Question:

Which of the following is not a way that carbon dioxide is transported in the body?

• Dissolved in plasma
• Attached to hemoglobin
• As bicarbonate
• As hydrogen ions

Answer:

• as hydrogen ions

Hydrogen ions are single element ions. They cannot carry anything

Question:

Which of the following may affect adversely the ability of pulmonary artery occlusive pressure (PAOP) to reflect preload?

• Measuring the PAOP at the end of inspiration
• Changes in the patient's afterload
• Changes in the compliance of the patient's ventricle
• Loss of blood rather than fluid

Answer:

• Changes in the compliance of the patient's ventricle 3 / 4

Preload is a volume concept, but we routinely use atrial pressure to evaluate preload. The logical conclusion is that volume and pressure are directly and proportionally related. Although this may be true in a normally compliant ventricle, there will be a disproportionate increase in pressure with an increase in volume in a noncompliant ventricle. Remember that compliance is the change in pressure for a given change in volume. Use of volumetric parameters measured with a right ejection fraction catheter would allow measurement of volumes as a reflection of preload.

Question:

Which of the following would not be associated with a false-positive result for an acute myocardial infarction using the total creatine kinase (CK)?

• Hypothyroidism
• Hemorrhagic stroke
• Cardioversion
• Ulcerative colitis

Answer:

• Ulcerative colitis

CK may be elevated by chronic alcoholism, cardioversion, strokes, hypothyroidism, intramuscular injections, skeletal muscle injury, and trauma.
