Correct Answer: C

Rationale: Placenta previa is a disorder where the placenta implants in the lower uterine segment, causing painless bleeding in the third trimester of pregnancy. The bleeding results from tearing of the placental villi from the uterine wall as the lower uterine segment contracts and dilates. It can be slight or profuse and can include bright red, painless bleeding. While anemia (choice
A) may be a consequence of chronic bleeding from placenta previa, it is not a direct indicator. Edema (choice
B) and fatigue (choice
D) are nonspecific symptoms that can occur in pregnancy but are not specific to placenta previa.

Correct Answer: A

Rationale: The correct answer is 'Hypotension and Angina.' Norvasc is a medication known to cause hypotension (low blood pressure) and angina (chest pain) as side effects. These side effects are important for the patient to watch out for as they can indicate potential issues related to the medication.
Choice B ('Hypertension') is incorrect as Norvasc is actually used to treat hypertension, not cause it.
Choice C ('Lower extremity edema') is not a common side effect of Norvasc.
Choice D ('Peripheral sensory loss and SOB') is not typically associated with Norvasc's side effects.

Correct Answer: B

Rationale: The correct first action for the nurse to take in this situation is to retake the patient's vitals, including blood pressure. Dizziness can be a sign of hypotension, which may be a contraindication for administering Morphine. Checking the chest x-ray results (
Choice
A) would not be the priority in this case as addressing the dizziness is more urgent. Performing a neurological screening (
Choice
C) may be important but not the first step when a patient presents with dizziness and an order for Morphine. Requesting the physician to assess the patient (
Choice
D) should come after the initial assessment and vitals retake.

Correct Answer: D

Rationale: Polyphagia, polyuria, and metabolic acidosis are common clinical signs of diabetes mellitus. Polyphagia refers to excessive hunger, polyuria is excessive urination, and metabolic acidosis can occur due to poorly controlled diabetes. Lower extremity edema, on the other hand, is not a typical clinical sign of diabetes mellitus. Edema in the lower extremities is more commonly associated with conditions like heart failure or kidney disease rather than diabetes mellitus.

Correct Answer: B

Rationale: The correct answer is 'Sagittal.' The sagittal plane divides the body into left and right halves, and movements in this plane involve flexion and extension. In this case, limited shoulder flexion on the left indicates a restriction in the forward and backward movement of the arm, which occurs in the sagittal plane.
Choice A, 'Horizontal,' is incorrect as it refers to movements parallel to the ground.
Choice C, 'Frontal,' is incorrect as it involves side-to-side movements.
Choice D, 'Vertical,' is incorrect as it typically refers to up and down movements.
