MOST TESTED QUESTIONS AND ANSWERS | GRADED A+ | ASSURED
SUCCESS WITH DETAILED RATIONALES
1. A nurse is caring for an infant after a surgical procedure. After ensuring the ordered dose is
appropriate, the nurse administers a narcotic analgesic intravenously. Fifteen minutes later, the
infant is asleep in the parent's arms, respirations are 22/min, and heart rate is 110 bpm. These
findings are most likely due to:
A. Immaturity of the blood-brain barrier in the infant
B. Drug allergy
C. Overhydration
D. Infection
Answer: A. Immaturity of the blood-brain barrier in the infant
Rationale: Infants have an immature blood-brain barrier, making them more sensitive to central
nervous system depressants like narcotics. Allergic reactions or infection would present
differently, and overhydration would affect other systems.
2. A child will receive 750 mg of an antibiotic for 10 days. The drug is available in two
concentrations. Which dosing regimen is most appropriate to discuss with the provider?
A. 500 mg/5 mL, give 7.5 mL twice daily
B. 250 mg/5 mL, give 15 mL twice daily
C. 500 mg/5 mL, give 5 mL once daily
D. 250 mg/5 mL, give 7.5 mL three times daily
Answer: A. 500 mg/5 mL, give 7.5 mL twice daily
Rationale: Dose calculation must match the required total dose (750 mg). Using 500 mg/5 mL,
7.5 mL provides 750 mg per dose. Other options either underdose or overdose.
3. Parents ask why over-the-counter cough suppressants with sedative effects are not
recommended for infants. What is the correct response?
A. "Infants are more susceptible to central nervous system effects than adults"
B. "Infants cannot swallow tablets"
C. "Cough suppressants are ineffective in infants"
D. "They can cause constipation"
,ESTUDYR
Answer: A. "Infants are more susceptible to central nervous system effects than adults"
Rationale: Sedatives can easily depress the CNS in infants due to immature metabolism and
organ systems. Swallowing and constipation are secondary concerns.
4. A nurse caring for a 5-year-old notes discoloration of several teeth. The nurse should ask
about which group of medications?
A. Penicillins
B. Tetracyclines
C. Sulfonamides
D. Cephalosporins
Answer: B. Tetracyclines
Rationale: Tetracyclines can bind to calcium in teeth during development, causing permanent
discoloration. Other antibiotics do not have this effect.
5. Parents ask about using a topical antihistamine for an infant with a pruritic rash from allergies.
The nurse should respond:
A. "Topical antihistamines are safe for infants"
B. "Applying an antihistamine to the skin can cause toxicity in this age group"
C. "Oral antihistamines are more toxic than topical"
D. "There is no risk with any antihistamine"
Answer: B. "Applying an antihistamine to the skin can cause toxicity in this age group"
Rationale: Infants absorb medications more easily through the skin, increasing the risk of
systemic toxicity.
6. An infant is receiving a medication with a narrow therapeutic range that is excreted by the
kidneys. Which should the nurse assess?
A. Liver function tests
B. Signs of drug toxicity
C. Skin integrity
D. Gastrointestinal function
Answer: B. Signs of drug toxicity
, ESTUDYR
Rationale: Narrow therapeutic index drugs require monitoring for toxicity. Renal immaturity in
infants increases risk.
7. When teaching nursing students to calculate pediatric doses using body surface area, which
statement indicates understanding?
A. "This formula helps approximate the first dose; other doses should be based on clinical
observations"
B. "It gives exact dosing for every dose"
C. "It is not used in clinical practice"
D. "It replaces the need for vital sign monitoring"
Answer: A. "This formula helps approximate the first dose; other doses should be based on
clinical observations"
Rationale: Pediatric dosing formulas provide an initial safe dose, but ongoing assessment is
necessary.
8. Which statement shows understanding that drugs effective in adults may not work the same in
children?
A. "Drugs effective in adults may not work in children, even if the dose is proportional for
weight and size"
B. "Children always need higher doses than adults"
C. "All adult medications are safe for children"
D. "Dosing by weight is unnecessary"
Answer: A. "Drugs effective in adults may not work in children, even if the dose is
proportional for weight and size"
Rationale: Children metabolize drugs differently, so efficacy and safety may differ despite
weight-based dosing.
9. Pediatric drug research has shown:
A. Most drugs are safe in children
B. Significant unanticipated and potentially lethal side effects occur in children
C. Children metabolize all drugs faster than adults
D. Drugs have identical effects in children and adults
