HESI Focus on Maternity Exam

Correct Answer: C

Rationale: The correct answer is C. Regular, strong contractions with the presence of cervical change indicate that the woman is experiencing true labor. Choice A indicates the passing of the mucus plug, which is a sign of early labor but not definitive for true labor. Choice B, the breaking of the bag of waters, is a sign of labor but does not confirm whether it is true or false labor. Choice D, the baby dropping and increased urination frequency, suggests lightening, a sign that labor may be approaching, but it does not confirm true labor.

Correct Answer: B

Rationale: Individuals with cystic fibrosis have a genetic disorder that causes mucus to be thick and sticky, leading to blockages in the lungs and digestive system. This mucus buildup makes them more susceptible to severe respiratory infections, which can ultimately result in premature death in their 20s. Tay-Sachs disease (Choice A) is a genetic disorder that affects the nervous system, not typically causing respiratory infections. Turner syndrome (Choice C) and Klinefelter syndrome (Choice D) are chromosomal disorders that do not directly lead to the respiratory issues observed in cystic fibrosis.

Correct Answer: D

Rationale: Reassuring the mother that the baby's urine color can be an indicator of adequate hydration can help her feel more confident in her breastfeeding.

Correct Answer: C

Rationale: In a client with preeclampsia receiving magnesium sulfate, a urinary output of 20 mL/hr is a concerning finding as it may indicate renal impairment or magnesium toxicity. Adequate urinary output is crucial for eliminating excess magnesium and preventing toxicity. The nurse should report this finding to the provider for further evaluation. A blood pressure of 148/94 mm Hg is elevated but expected in a client with preeclampsia. A respiratory rate of 14/min is within the normal range. 2+ deep tendon reflexes are a common finding in clients receiving magnesium sulfate and are not a cause for concern unless they progress to hyperreflexia or clonus.

Correct Answer: A

Rationale: Calculation: (6 mg/dose) / (10 mg/mL) = 0.6 mL per dose. The correct answer is 0.6 mL. This calculation is obtained by dividing the dose needed (6 mg) by the concentration available (10 mg/mL). The resulting value is 0.6 mL per dose. Choices B, C, and D are not applicable as the correct answer has been calculated accurately.
