Correct Answer: A

Rationale: The correct answer is A: Using the Glasgow Coma Scale. The Glasgow Coma Scale is a standardized tool used to assess a patient's level of consciousness by evaluating their eye response, verbal response, and motor response. This scale provides a numeric value that helps in determining the severity of brain injury or altered mental status. Choices B, C, and D are incorrect because while assessing the patient's orientation, checking pupillary response, and monitoring vital signs are important components of a comprehensive patient assessment, they do not specifically target the assessment of consciousness level, which is best done using the Glasgow Coma Scale.

Correct Answer: C

Rationale: The correct answer is C: Left lateral. Placing the client in the left lateral position helps promote optimal cardiac output during pregnancy by avoiding pressure on the vena cava. This position improves venous return to the heart and subsequently cardiac output. Option A, Semi-Fowler's position, may not be the best choice for a client with cardiac disease as it does not alleviate pressure on the vena cava. Option B, supine with head elevated, can also compress the vena cava, reducing cardiac output. Option D, right lateral position, does not provide the same benefits as the left lateral position for cardiac output during pregnancy.

Correct Answer: D

Rationale: Spinach is an excellent choice to recommend as it is rich in non-heme iron, which can help improve iron levels in clients with iron deficiency anemia. Eggs (Choice A) are a good source of protein but do not contain as much iron as spinach. Carrots (Choice B) are rich in vitamin A but are not a significant source of iron. White bread (Choice C) is not a good source of iron compared to spinach.

Correct Answer: A

Rationale: The correct answer is A: Administer analgesics regularly. Postoperative pain management often requires a scheduled, around-the-clock administration of analgesics to maintain a consistent level of pain relief and minimize the risk of breakthrough pain. Choice B, administering pain medication PRN (as needed), may lead to inadequate pain control as the medication is not given preemptively. Choice C, encouraging deep breathing exercises, can be beneficial for pain management but should be used as an adjunct to analgesic therapy. Choice D, providing distraction techniques, may help some patients cope with pain but should not be the primary method of pain management postoperatively.

Correct Answer: A

Rationale: Administering oxygen is the best initial nursing intervention for a patient with suspected pulmonary embolism because it helps address hypoxia, a common complication of this condition. Oxygen therapy can improve oxygenation and support vital organ function. Administering anticoagulants (Choice B) is a treatment option for confirmed pulmonary embolism but not the initial intervention. Repositioning the patient (Choice C) and checking oxygen saturation (Choice D) are important assessments but do not address the immediate need to improve oxygenation in a patient with suspected pulmonary embolism.
