The nurse is caring for a client scheduled to undergo a renal biopsy. To minimize the risk of postprocedure complications, the nurse reports which laboratory results to the primary health care provider before the procedure?
- A. Prothrombin time: 15 seconds
- B. Potassium: 3.8 mEq/L (3.8 mmol/L)
- C. Serum creatinine: 1.2 mg/dL (106 mcmol/L)
- D. Blood urea nitrogen (BUN): 18 mg/dL (6.48 mmol/L)
Correct Answer: A
Rationale: Postprocedure hemorrhage is a complication after renal biopsy. Because of this, prothrombin time is assessed before the procedure. The normal prothrombin time range is 11 to 12.5 seconds. The nurse ensures that these results are available and reports abnormalities promptly. Options 2, 3, and 4 identify normal values. The normal potassium is 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L); the normal serum creatinine is 0.5 to 1.2 mg/dL (44 to 106 mcmol/L); and the normal BUN is 10-20 mg/dL (3.6-7.1 mmol/L).

In preparation to administer an intermittent tube feeding, the nurse aspirates 40 mL of undigested formula from the client's nasogastric tube. Which intervention should the nurse implement as a result of this finding?
- A. Discard the aspirate and record as client output.
- B. Mix with new formula to administer the feeding.
- C. Dilute with water and inject into the nasogastric tube.
- D. Reinstill the aspirate through the nasogastric tube via gravity and syringe.
Correct Answer: D
Rationale: After checking residual feeding contents, the nurse reinstills the gastric contents into the stomach by removing the syringe bulb or plunger and pouring the gastric contents via the syringe into the nasogastric tube. Gastric contents should be reinstilled (unless they exceed an amount of 100 mL or as defined by agency policy) to maintain the client's fluid and electrolyte balance. The nurse avoids mixing gastric aspirate with fresh formula to prevent contamination. Because the gastric aspirate is a small volume, it should be reinstilled; however, mixing the formula with water can also disrupt the client's fluid and electrolyte balance unless the client is dehydrated.
The nurse is providing care for a client who has just experienced a liver biopsy performed at the bedside. Which position should the nurse place the client in after the biopsy?
- A. Supine with the head elevated on one pillow
- B. Semi-Fowler's with two pillows under the legs
- C. Left side-lying with a small pillow under the puncture site
- D. Right side-lying with a folded towel under the puncture site
Correct Answer: D
Rationale: The liver is located on the right side of the body. After a liver biopsy, the nurse positions the client on the right side with a small pillow or folded towel under the puncture site for 2 hours. This position compresses the liver against the abdominal wall at the biopsy site to tamponade bleeding from the puncture site.
A client prescribed warfarin sodium has been instructed to limit the intake of foods high in vitamin K. The nurse determines that the client understands the instructions if the client indicates that which food items need to be avoided? Select all that apply.
- A. Tea
- B. Turnips
- C. Oranges
- D. Cabbage
- E. Broccoli
- F. Strawberries
Correct Answer: A,B,D,E
Rationale: Warfarin sodium is an anticoagulant that interferes with the hepatic synthesis of vitamin K-dependent clotting factors. The client is instructed to limit the intake of foods high in vitamin K while taking this medication. These foods include coffee or tea (caffeine), turnips, cabbage, broccoli, greens, fish, and liver.
A client who is being treated for acute heart failure has the following vital signs: blood pressure (BP), 85/50 mm Hg; pulse, 96 beats per minute; respirations, 26 breaths per minute. The primary health care provider prescribes digoxin. To evaluate a therapeutic response to this medication, which changes in the client's vital signs should the nurse expect?
- A. BP 85/50 mm Hg, pulse 60 beats per minute, respirations 26 breaths per minute
- B. BP 98/60 mm Hg, pulse 80 beats per minute, respirations 24 breaths per minute
- C. BP 130/70 mm Hg, pulse 104 beats per minute, respirations 20 breaths per minute
- D. BP 110/40 mm Hg, pulse 110 beats per minute, respirations 20 breaths per minute
Correct Answer: B
Rationale: The main function of digoxin is inotropic. It produces increased myocardial contractility that is associated with an increased cardiac output. This causes a rise in the BP in a client with heart failure. Digoxin also has a negative chronotropic effect (decreases heart rate) and will therefore cause a slowing of the heart rate. As cardiac output improves, there should be an improvement in respirations as well. The remaining choices do not reflect the physiological changes attributed to this medication.
The nurse assessing the apical heart rates of several different newborn infants notes that which heart rate is normal for this newborn population?
- A. 90 beats per minute
- B. 140 beats per minute
- C. 180 beats per minute
- D. 190 beats per minute
Correct Answer: B
Rationale: The normal heart rate in a newborn infant is approximately 100 to 160 beats per minute. Options 1, 3, and 4 are incorrect. Option 1 indicates bradycardia, and options 3 and 4 indicate tachycardia (greater than 100 beats per minute).
