Correct Answer: A

Rationale: The correct answer is A: Inspection, Palpation, Percussion, Auscultation. A focused respiratory assessment should start with inspection (observing the breathing pattern), followed by palpation (feeling for abnormalities like crepitus), percussion (evaluating for dullness or hyperresonance), and auscultation (listening to lung sounds). This systematic approach helps to identify signs of respiratory distress, such as abnormal breath sounds, increased respiratory rate, use of accessory muscles, and cyanosis. Choices B, C, and D are incorrect because they do not follow the standard order and sequence of a focused respiratory assessment.

Correct Answer: A

Rationale: The correct answer is A. Positive urine glucose and acetone could indicate gestational diabetes or preeclampsia, both of which are complications. Choice B, pedal edema, is common in pregnancy but may also be a sign of preeclampsia if severe. Choice C, an increase in vaginal discharge, is a normal finding in pregnancy due to hormonal changes. Choice D, pressure against the diaphragm when the baby moves, is a normal sensation due to the growing uterus displacing abdominal contents.

Correct Answer: D

Rationale: In cases of magnesium sulfate toxicity, calcium gluconate is the antidote that should be administered promptly. Positioning the client supine (Choice A) is not the priority in this scenario. Administering dextrose 5% in water (Choice B) is not indicated for magnesium sulfate toxicity. Methylergonovine IM (Choice C) is used for postpartum hemorrhage, not for magnesium sulfate toxicity.

Correct Answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

Correct Answer: A

Rationale: Corrected Rationale: Bradycardia is a common sign of hypoglycemia due to the body's response to low blood sugar. During hypoglycemia, the body releases epinephrine, leading to sympathetic nervous system activation. This can result in bradycardia as a compensatory mechanism to preserve glucose for vital organs such as the brain. Tachycardia, hypotension, and diaphoresis are more commonly associated with hypoglycemia when it progresses to severe stages and the body's compensatory mechanisms are overwhelmed.
