1. The healthcare provider is assessing a client who is receiving total parenteral nutrition (TPN). Which finding requires immediate intervention?
- A. Blood glucose level of 150 mg/dL.
- B. Weight gain of 2 pounds in 24 hours.
- C. Decreased urine output.
- D. Temperature of 100.3°F (37.9°C).
Correct answer: C
Rationale: Decreased urine output in a client receiving total parenteral nutrition (TPN) requires immediate intervention because it can indicate potential complications such as fluid overload or kidney dysfunction. Monitoring urine output is crucial in assessing renal function and fluid balance in patients on TPN. A blood glucose level of 150 mg/dL is within a normal range and may not require immediate intervention. Weight gain of 2 pounds in 24 hours could be a concern but may not be as urgent as addressing decreased urine output. A temperature of 100.3°F (37.9°C) is slightly elevated but may not be directly related to TPN administration unless there are other symptoms of infection present.
2. Water is a polar molecule that can be:
- A. cohesive and corrosive
- B. cohesive and adhesive
- C. electrostatic and ionic
- D. repellent and attractive
Correct answer: B
Rationale: Water is a polar molecule due to an uneven distribution of electrons, allowing it to form hydrogen bonds. This property makes water both cohesive (attracted to itself) and adhesive (attracted to other substances). Choice A is incorrect because water is not corrosive; rather, it is a solvent. Choices C and D are incorrect as they do not describe the cohesive and adhesive properties of water.
3. A two-year-old child with heart failure (HF) is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?
- A. Determine the pulse deficit
- B. Administer the scheduled dose
- C. Calculate the safe dose range
- D. Review the serum digoxin level
Correct answer: B
Rationale: The correct action for the nurse to take is to administer the scheduled dose of digoxin. A heart rate of 128 bpm in a two-year-old child with heart failure falls within the safe range for digoxin administration. It indicates that the child's heart rate is not excessively low, which could be a concern for administering digoxin. Therefore, proceeding with the scheduled dose is appropriate in this scenario. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is already obtained. Calculating the safe dose range (Choice C) is not required as the heart rate is within the safe range. Reviewing the serum digoxin level (Choice D) is not needed at this point since the heart rate indicates that administering the next dose is appropriate.
4. What is the primary method of asexual reproduction used by most bacteria?
- A. Meiosis
- B. Mitosis
- C. Binary fission
- D. Interphase
Correct answer: C
Rationale: The correct answer is C: Binary fission. This is the main process through which most bacteria reproduce asexually. During binary fission, a single cell divides into two identical cells, each containing a copy of the genetic material. Choices A and B, meiosis and mitosis, are processes involved in sexual reproduction and are not used by bacteria for asexual reproduction. Choice D, interphase, is a stage of the cell cycle where the cell prepares for division and is not a method of reproduction.
5. Which assessment finding is most indicative of deep vein thrombosis (DVT) in a client's right leg?
- A. Dorsiflexes the right foot and left on command
- B. A 3 by 5 cm ecchymosis area covering the right calf
- C. Right calf is 3 cm larger in circumference than the left
- D. Bilateral lower extremity has 3+ pitting edema
Correct answer: C
Rationale: The correct answer is C because a significant increase in the circumference of the right calf compared to the left calf is a classic sign of deep vein thrombosis (DVT). Option A is incorrect as dorsiflexing the right foot and left on command does not specifically indicate DVT. Option B describes an ecchymosis area which is more indicative of a bruise rather than DVT. Option D suggests bilateral lower extremity edema, which is not specific to DVT and can be seen in various conditions such as heart failure or renal issues.
