1. When reading a lab report, you notice that a patient's sample is described as having anisocytosis. Which of the following most accurately describes the patient's condition?
- A. The patient has an abnormal condition of skin cells.
- B. The patient's red blood cells vary in size.
- C. The patient has a high level of fat cells and is obese.
- D. The patient's cells are indicative of necrosis.
Correct answer: B
Rationale: Anisocytosis is a term that indicates variation in the size of red blood cells. When a patient is described as having anisocytosis, it means their red blood cells exhibit differences in size. This condition can be detected in blood samples and may indicate underlying blood disorders. The other choices are incorrect: Choice A refers to a skin cell condition, Choice C relates to obesity and fat cells, and Choice D suggests necrosis, none of which are associated with anisocytosis or red blood cell abnormalities. It is important to recognize specific terms like anisocytosis in laboratory reports to understand the potential implications for the patient's health.
2. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?
- A. The bicarbonate level (HCO3) is 31 mEq/L
- B. The arterial oxygen saturation (SaO2) is 92%
- C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
- D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg
Correct answer: D
Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.
3. A mother brings her child to the well-child clinic and expresses concern to the nurse because the child has been playing with another child diagnosed with hepatitis. The nurse prepares to perform an assessment on the child, knowing that which finding would be of least concern for hepatitis?
- A. Jaundice
- B. Hepatomegaly
- C. Dark-colored, frothy urine
- D. Left upper abdominal quadrant pain
Correct answer: D
Rationale: Assessment findings in a child with hepatitis typically include right upper quadrant tenderness and hepatomegaly. The child may also present with pale, clay-colored stools and dark, frothy urine. Jaundice, which can be observed in the sclerae, nail beds, and mucous membranes, is a common sign of hepatitis. Left upper abdominal quadrant pain is not a typical finding associated with hepatitis; therefore, it would be of least concern in this scenario. The other options are more commonly associated with hepatitis and are important signs to monitor for in a child with possible exposure to the virus.
4. While suctioning the endotracheal tube of an adult client, what level of pressure should the nurse apply?
- A. 70-80 mmHg
- B. 100-120 mmHg
- C. 150-170 mmHg
- D. 200 mmHg
Correct answer: B
Rationale: When suctioning the endotracheal tube of an adult client, the nurse should set the suction apparatus at a level no higher than 150 mmHg, with a preferable level between 100 and 120 mmHg. Suction pressure that is too high can contribute to the client's hypoxia. Alternatively, too low suction pressure may not clear adequate amounts of secretions. Choice A (70-80 mmHg) is too low and may not effectively clear secretions. Choices C (150-170 mmHg) and D (200 mmHg) are too high and can potentially harm the client by causing hypoxia or damaging the airway.
5. The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:
- A. Urinary output of 30 ml per hour
- B. No complaints of thirst
- C. Increased hematocrit
- D. Good skin turgor around burn
Correct answer: A
Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.
