1. The healthcare provider is caring for a client with jaundice. Which serum laboratory value is likely to be elevated for this client?
- A. Amylase
- B. Creatinine
- C. Blood urea nitrogen
- D. Bilirubin
Correct answer: D
Rationale: Bilirubin is a key serum laboratory value that is likely to be elevated in clients with jaundice. Jaundice is characterized by a yellowish discoloration of the skin and eyes due to an excess of bilirubin, a breakdown product of hemoglobin. Elevated amylase levels are associated with pancreatic conditions, not specifically jaundice. Creatinine and blood urea nitrogen are markers of kidney function and are not directly related to jaundice.
2. The nurse is caring for a 10-year-old diagnosed with acute glomerulonephritis. Which outcome is the priority for this child?
- A. Activity tolerance as evidenced by appropriate age-level activities being performed
- B. Absence of skin breakdown as evidenced by intact skin and absence of redness
- C. Maintaining adequate nutritional status as evidenced by stable weight without gain or loss
- D. Maintaining fluid balance as evidenced by a urine output of 1 to 2 ml/kg/hr
Correct answer: D
Rationale: In acute glomerulonephritis, maintaining fluid balance is the priority to prevent complications like fluid overload or dehydration. Monitoring urine output within the range of 1 to 2 ml/kg/hr is crucial in assessing renal function. While activity tolerance, skin integrity, and nutritional status are important aspects of care, fluid balance takes precedence due to its direct impact on the renal condition and overall health outcome for the child.
3. Oxygen at liters/min per nasal cannula PRN difficult breathing is prescribed for a client with pneumonia. Which nursing intervention is effective in preventing oxygen toxicity?
- A. Avoiding the administration of high levels of oxygen for extended periods.
- B. Administering a sedative at bedtime to slow the client's respiratory rate.
- C. Removing the nasal cannula during the night to prevent oxygen buildup.
- D. Running oxygen through a hydration source prior to administration.
Correct answer: A
Rationale: The correct answer is A: Avoiding the administration of high levels of oxygen for extended periods. Oxygen toxicity can occur when high levels of oxygen are given for a prolonged period. It is important to monitor and adjust the oxygen levels as needed to prevent toxicity. Choice B is incorrect because administering a sedative to slow the respiratory rate does not directly prevent oxygen toxicity. Choice C is incorrect as removing the nasal cannula during the night can compromise the client's oxygenation. Choice D is incorrect as running oxygen through a hydration source does not prevent oxygen toxicity; instead, it may introduce risks associated with the hydration source.
4. Assessment findings of a 3-hour-old newborn include: axillary temperature of 97.7°F, heart rate of 140 beats/minute with a soft murmur, and irregular respiratory rate at 42 breaths/min. Based on these findings, what action should the nurse implement?
- A. Place a pulse oximeter on the heel
- B. Swaddle the infant in a warm blanket
- C. Record the findings on the flow sheet
- D. Check the vital signs in 15 minutes
Correct answer: C
Rationale: The correct answer is to record the findings on the flow sheet. These assessment findings are within normal limits for a 3-hour-old newborn. The axillary temperature of 97.7°F, heart rate of 140 beats/minute with a soft murmur, and irregular respiratory rate of 42 breaths/min are all expected in a newborn. No immediate intervention is needed, so the nurse should document these normal findings for future reference. Placing a pulse oximeter on the heel or swaddling the infant in a warm blanket is not indicated as the vital signs are within normal limits. Checking the vital signs in 15 minutes is unnecessary since the current findings are normal.
5. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?
- A. It dissolves blood clots
- B. It prevents the blood from clotting
- C. It thins the blood
- D. It decreases the risk of infection
Correct answer: B
Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.
