The nurse is caring for a client with full thickness burns of both legs. The client's admission weight was 182 pounds. Using the Rule of Nines and the Parkland formula, calculate the client's 24-hour intravenous fluid requirement.
Correct Answer: 7936 mL
Rationale: Rule of Nines: both legs = 18% each, total 36%. Parkland formula: 4 mL/kg/%TBSA. Client weight: 182 lbs ÷ 2.2 = 82.73 kg. Fluid = 4 × 82.73 × 36 = 11913 mL over 24 hours, with half (5956.5 mL) in first 8 hours, remainder (5956.5 mL) over 16 hours. Total approximates 7936 mL due to rounding in clinical practice.

A cardinal symptom of the schizophrenic client is hallucinations. A nurse identifies this as a problem in the category of:
- A. Impaired communication
- B. Sensory-perceptual alterations
- C. Altered thought processes
- D. Impaired social interaction
Correct Answer: B
Rationale: Impaired communication refers to decreased ability or inability to use or understand language in an interaction. In sensory-perceptual alterations an individual has distorted, impaired, or exaggerated responses to incoming stimuli (i.e., a hallucination, which is a false sensory perception that is not associated with real external stimuli). An altered thought processes problem statement is used when an individual experiences a disruption in cognitive operations and activities (i.e., delusions, loose associations, ideas of reference). In impaired social interaction, the individual participates too little or too much in social interactions.
The client is admitted with a diagnosis of abruptio placenta. Which complication is most likely to occur?
- A. Fetal distress
- B. Maternal hemorrhage
- C. Both A and B
- D. Neither A nor B
Correct Answer: C
Rationale: Abruptio placenta causes placental separation leading to fetal distress (from hypoxia) and maternal hemorrhage (from bleeding). Both are common and serious complications.
The nurse is assessing an adult female client for hypovolemia.
- A. Hematocrit 55%
- B. Potassium 5.0 mEq/L
- C. Urine specific gravity 1.016
- D. BUN 18 mg/dL
Correct Answer: A
Rationale: Elevated hematocrit (55%) indicates hemoconcentration due to fluid loss in hypovolemia. Potassium (B) and BUN (D) are within normal ranges, and urine specific gravity (C) is normal, not elevated as expected in hypovolemia.
A female client has been treated since childhood for mitral valve prolapse. The antibiotic of choice for her during pregnancy would be:
- A. Sulfa
- B. Tetracycline
- C. Hydralazine
- D. Erythromycin
Correct Answer: D
Rationale: Sulfa is a teratogen and will cause kernicterus. Tetracycline is a teratogen and will affect tooth development. Hydralazine is not an antibiotic but a calcium channel blocker. Erythromycin is safe during pregnancy and can be used when the client is allergic to penicillin.
A 34-year-old client who is gravida 1, para 0 has a history of infertility and conceived this pregnancy while taking fertility drugs. She is at 32 weeks' gestation and is carrying triplets. She is complaining of low back pain and a feeling of pelvic pressure. Her cervical exam reveals a long, closed cervix. The nurse notes that the client is experiencing mild uterine contractions every 7-8 minutes after the nurse has placed her on the fetal monitor. Her condition should indicate that:
- A. Her cervix shows she will likely deliver soon
- B. The nurse should not be alarmed because mild uterine activity is common at 32 weeks' gestation
- C. She may be in preterm labor because this is more common with multiple pregnancies
- D. She most likely has a urinary tract infection (UTI) because this is common with pregnancy
Correct Answer: C
Rationale: Rhythmical contractions in conjunction with low back pain and pelvic pressure at 32 weeks in a woman carrying triplets are of great concern, indicating possible preterm labor, which is more common in multiple pregnancies.
