,Question 1
A nurse is caring for a client receiving Total Parenteral Nutrition (TPN). The current TPN bag is
empty, and the next solution is temporarily unavailable from the pharmacy. Which of the
following actions should the nurse take?
A. Decrease the infusion rate of the current bag until the new bag arrives.
B. Discontinue the infusion line and flush with heparinized saline.
C. Administer 10% dextrose in water (D10W) at the same infusion rate.
D. Speed up the infusion rate of the remaining solution to buy time.
Detailed Rationale:
• Correct (C): TPN solutions contain highly concentrated dextrose. Abruptly stopping
TPN can cause severe, precipitous hypoglycemia due to the high levels of endogenous
insulin produced by the pancreas in response to the hypertonic solution. Administering
D10W maintains circulating blood glucose levels until the new TPN bag is available.
• Incorrect (A, D): Speeding up or slowing down the TPN rate is strictly contraindicated.
Modifying the prescribed rate can cause severe fluctuations in blood glucose levels
(hyperglycemia or hypoglycemia) and hyperosmolar HHNS.
• Incorrect (B): Discontinuing the line without a continuous glucose source will trigger
severe rebound hypoglycemia.
Question 2
A nurse is reviewing the laboratory results of a client and notes an elevated erythrocyte
sedimentation rate (ESR). The nurse should understand that this finding indicates which of the
following physiological processes?
A. An acute decline in red blood cell production.
B. An active systemic or localized inflammatory response.
C. A high risk for immediate hypercoagulability and clotting.
D. An early stage of acute localized iron-deficiency anemia.
Detailed Rationale:
• Correct (B): The erythrocyte sedimentation rate (ESR) is a non-specific acute-phase
reactant test. It rises when plasma proteins (such as fibrinogen) increase during an
inflammatory response, causing red blood cells to clump together and settle to the bottom
of a test tube more rapidly.
• Incorrect (A): ESR does not measure the rate of bone marrow RBC production; it
reflects protein alterations in the serum.
2
, • Incorrect (C): While fibrinogen is involved, an elevated ESR is a marker of
inflammation, not a direct diagnostic tool or predictor for immediate acute thrombotic
events.
• Incorrect (D): Anemia can independently affect ESR values, but an elevated ESR does
not indicate or diagnose iron-deficiency anemia.
Question 3
A nurse is providing discharge teaching to a client who has a new prescription for ciprofloxacin.
Which of the following instructions should the nurse include?
A. Take the medication with a glass of milk to minimize gastrointestinal upset.
B. Administer the medication 2 hours before or 6 hours after taking an antacid.
C. Restrict fluid intake during therapy to maximize drug concentration in the urine.
D. Take an antacid concurrently with the medication to prevent gastric erosion.
Detailed Rationale:
• Correct (B): Ciprofloxacin is a fluoroquinolone antibiotic that chelates with polyvalent
cations (such as magnesium, aluminum, calcium, and iron) found in antacids,
supplements, and dairy products. This chelation severely decreases its absorption.
Spacing the medication 2 hours before or 6 hours after antacids prevents this interaction.
• Incorrect (A, D): Calcium-containing foods, dairy, and antacids reduce the drug's
therapeutic efficacy by blocking absorption in the gastrointestinal tract.
• Incorrect (C): Fluids should be increased, not restricted, during ciprofloxacin therapy to
prevent crystalluria.
Question 4
A nurse is preparing to administer enoxaparin to a client. Which of the following techniques
should the nurse utilize?
A. Administer the medication subcutaneously at the exact same time every day.
B. Massage the injection site firmly for 15 seconds following drug delivery.
C. Expel the nitrogen air bubble from the prefilled syringe prior to injection.
D. Aspirate for blood return after inserting the needle into the tissue.
Detailed Rationale:
• Correct (A): Enoxaparin is a low-molecular-weight heparin (LMWH) that must be
administered via subcutaneous injection at the same time daily to maintain therapeutic,
predictable anticoagulant plasma levels.
