1. What is the digestive action of bile?
- A. It breaks down carbohydrates
- B. It breaks down proteins
- C. It breaks down lipids
- D. It aids in fat digestion
Correct answer: D
Rationale: Bile, which is produced by the liver and stored in the gallbladder, aids in the digestion of fats. It does this by emulsifying the fats, which makes them easier for the digestive enzymes, such as lipase, to break down. While choices A, B, and C could be seen as partially correct since fats are a type of lipid and the process of breaking down fats could be seen as breaking down lipids, the most accurate answer is D, as the primary function of bile is to aid in fat digestion, not the digestion of all types of lipids or the digestion of proteins or carbohydrates.
2. At a well-child visit, parents ask the nurse how to know if a daycare facility is a good choice for their infant. Which observation should the nurse stress as especially important to consider when making the selection?
- A. Developmentally appropriate toys
- B. Nutritious snacks served to the children
- C. Handwashing by providers after diaper changes
- D. Certified caregivers for each of the age groups at the facility
Correct answer: C
Rationale: Ensuring that providers practice proper handwashing after diaper changes is crucial in preventing the spread of infections and maintaining a hygienic environment for the infants.
3. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following laboratory values indicates the TPN is effective?
- A. Albumin 3.5 g/dL
- B. Hemoglobin 8 g/dL
- C. WBC count 15,000/mm3
- D. Blood glucose 110 mg/dL
Correct answer: D
Rationale: The correct answer is D. A blood glucose level of 110 mg/dL indicates that the TPN is effective in maintaining normal glucose levels. Hemoglobin level (choice B) is related to anemia and not directly indicative of TPN effectiveness. Albumin level (choice A) is a marker of nutritional status over a longer term and may not reflect immediate TPN effectiveness. White blood cell count (choice C) is related to infection or inflammation and is not a direct indicator of TPN effectiveness.
4. After a pericardiocentesis, what interventions should the nurse implement?
- A. Monitor vital signs every 15 minutes for the first hour
- B. Evaluate the client’s cardiac rhythm
- C. Record the amount of fluid removed as output
- D. All of the above
Correct answer: D
Rationale: After a pericardiocentesis, the nurse should implement multiple interventions to monitor the client's condition closely. Monitoring vital signs every 15 minutes for the first hour is crucial to detect any immediate changes that may indicate complications. Evaluating the client's cardiac rhythm is important to identify any arrhythmias that may occur due to the procedure. Recording the amount of fluid removed is essential to calculate fluid balance and ensure accurate monitoring of the client's status. Therefore, all the interventions mentioned are necessary to detect and manage any potential issues post-pericardiocentesis. Choices A, B, and C are all essential components of post-procedural care and should be implemented to ensure the client's safety and well-being.
5. Which of the following describes inflammation of the bladder lining?
- A. Incontinence
- B. Pyelonephritis
- C. Urinary calculi
- D. Cystitis
Correct answer: D
Rationale: The correct answer is D, Cystitis. Cystitis specifically refers to the inflammation of the bladder lining. Choice A, Incontinence, refers to the loss of bladder control and is not related to inflammation. Choice B, Pyelonephritis, is the inflammation of the kidney and renal pelvis, not the bladder lining. Choice C, Urinary calculi, refers to the formation of stones in the urinary tract and is not related to bladder inflammation.
