The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?
- A. Blood glucose of 140 mg/dL
- B. White blood cell count of 8000/mm³
- C. Serum potassium of 3.8 mEq/L
- D. Serum calcium of 7.8 mg/dL
Correct Answer: D
Rationale: The correct answer is D: Serum calcium of 7.8 mg/dL. This finding indicates hypocalcemia, which can lead to life-threatening cardiac arrhythmias. Low calcium levels can be caused by TPN administration or poor calcium absorption following bowel resection. Immediate intervention may include administering IV calcium gluconate.
A: Blood glucose of 140 mg/dL is within the normal range and not an immediate concern.
B: White blood cell count of 8000/mm³ is within the normal range and does not require immediate intervention.
C: Serum potassium of 3.8 mEq/L is within the normal range and does not pose an immediate threat.

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: The correct answer is D. In acute glomerulonephritis, the kidneys are inflamed, affecting fluid balance. Monitoring urine output of 1 to 2 ml/kg/hr is crucial to assess kidney function and prevent fluid overload or dehydration. This is the priority outcome as it directly reflects kidney function and overall fluid balance.
A: Activity tolerance is important but not the priority in acute glomerulonephritis.
B: Absence of skin breakdown is important for overall health but not directly related to the condition.
C: Nutritional status is important, but fluid balance takes precedence in managing acute glomerulonephritis.
In summary, maintaining fluid balance is crucial in managing acute glomerulonephritis as it directly reflects kidney function, while the other options are important but not the priority in this scenario.
A client with type 2 diabetes mellitus is admitted for antibiotic treatment of a leg ulcer. Which signs and symptoms, indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS), should the nurse report to the healthcare provider? (Select one that doesn't apply.)
- A. Increased heart rate
- B. Visual disturbances
- C. Presence of uremic frost
- D. Decreased mentation
Correct Answer: C
Rationale: The correct answer is C: Presence of uremic frost. HHNS is characterized by severe hyperglycemia leading to osmotic diuresis and dehydration, not uremia. A: Increased heart rate is a non-specific sign of stress. B: Visual disturbances can be seen in diabetic retinopathy but are not specific to HHNS. D: Decreased mentation is common in HHNS due to severe dehydration and hyperglycemia leading to altered mental status.
The nurse offers diet teaching to a female college student who was diagnosed with iron-deficiency anemia following her voluntary adoption of a lacto-vegetarian diet. What nutrients should the nurse suggest this client eat to best meet her nutritional needs while allowing her to adhere to a lacto-vegetarian diet?
- A. Drink whole milk instead of skim milk to enhance the body's production of amino acids
- B. Take vitamin K 10mg PO daily to enhance production of red blood cells
- C. Increase amounts of dark yellow vegetables such as carrots to fortify iron stores
- D. Combine several legumes and grains such as beans and rice to form complete proteins
Correct Answer: D
Rationale: The correct answer is D: Combine several legumes and grains such as beans and rice to form complete proteins. This is the best option because a lacto-vegetarian diet excludes meat but includes dairy products. Legumes and grains complement each other in terms of amino acid profiles, allowing the individual to obtain all essential amino acids needed for protein synthesis. This combination ensures the client gets adequate protein intake necessary for red blood cell production without consuming meat.
A: Drinking whole milk instead of skim milk does not enhance amino acid production. Skim milk contains the same amino acids as whole milk.
B: Taking vitamin K does not enhance red blood cell production. Iron is the key nutrient needed for red blood cell production.
C: Increasing dark yellow vegetables such as carrots does not provide a significant amount of iron to fortify iron stores compared to legumes and grains.
A nurse is planning care for a client who is newly diagnosed with diabetes mellitus. Which instruction should the nurse include in this client¢â‚¬â„¢s teaching plan?
- A. Avoid all forms of sugar
- B. Check blood glucose levels once a week
- C. Rotate insulin injection sites
- D. Monitor urine ketone levels
Correct Answer: C
Rationale: The correct answer is C: Rotate insulin injection sites. This instruction is crucial to prevent lipohypertrophy, which can lead to inconsistent insulin absorption. By rotating injection sites, the client ensures proper insulin absorption and prevents complications. Checking blood glucose levels once a week (B) is not frequent enough for proper diabetes management. Avoiding all forms of sugar (A) is an outdated approach, as moderation is key. Monitoring urine ketone levels (D) is not as reliable as blood ketone testing for assessing diabetic ketoacidosis risk.
The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. International normalized ratio (INR)
- D. Activated partial thromboplastin time (aPTT)
Correct Answer: C
Rationale: Rationale:
1. Heparin primarily affects the intrinsic pathway of coagulation.
2. International Normalized Ratio (INR) is used to monitor the effectiveness of anticoagulation therapy.
3. INR is more specific for monitoring heparin therapy compared to other options.
4. Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) are not as accurate for heparin monitoring.
5. Partial Thromboplastin Time (PTT) is used to monitor heparin therapy, but INR is a more precise indicator of heparin's effect.
