Correct Answer: A

Rationale: Administering oxygen is crucial in managing a patient experiencing respiratory distress. Oxygen therapy helps to improve oxygen levels in the blood, supporting vital organ functions. While monitoring airway patency is important, administering oxygen takes precedence in ensuring the patient receives an adequate oxygen supply. Providing bronchodilators may be beneficial in certain respiratory conditions, but the immediate priority in distress is to address oxygenation. Calling for assistance is essential, but the immediate intervention to support the patient's respiratory function is administering oxygen.

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: 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: C

Rationale: The most likely consequence to discourage adolescents from smoking is the immediate effect of decreased athletic ability. This consequence is more tangible and relevant to high school students compared to long-term health risks like lung cancer or addiction. While choices A, B, and D are all negative outcomes of smoking, choice C is more likely to have a direct impact on adolescents due to its immediate and visible effects on their physical performance.

Correct Answer: B

Rationale: The correct answer is to consult with a dietitian to create a high-protein diet. A serum albumin level of 3 g/dL indicates hypoalbuminemia, which can impair wound healing. Consulting with a dietitian to optimize the client's protein intake is crucial in promoting wound healing for pressure ulcers. Increasing the protein intake in the diet (Choice A) may not be sufficient without proper guidance from a dietitian. Increasing the IV fluid infusion rate (Choice C) is not directly related to addressing the protein deficiency. Administering a protein supplement (Choice D) should be guided by a healthcare professional's recommendation after consulting with a dietitian.
