Correct Answer: B

Rationale: The correct answer is B: osteoporosis. Osteoporosis is a condition characterized by weakened bones, making individuals more susceptible to fractures, especially with minor trauma or falls. In the context of a patient prone to fractures, nurses should be particularly cautious about fall prevention. A: The aging process alone does not necessarily lead to an increased risk of fractures. While aging is a risk factor for osteoporosis, it is not the direct cause of fractures in this case. C: Changes in vision can contribute to an increased risk of falls, but it is not the primary reason for the patient being prone to fractures in this scenario. D: Hematologic conditions may affect bone health, but they are not typically the primary cause of increased fracture risk in patients.

Correct Answer: C

Rationale: The correct answer is C: Umbilicus. The nurse begins assessing the uterine fundus at the level of the umbilicus as it is a standard reference point for postpartum fundal height measurement. This location allows for consistency and accuracy in tracking the descent of the uterus back into the pelvic cavity. Starting at the umbilicus also helps in monitoring the involution process and prevents potential errors in fundal height assessment. Symphysis pubis (A) is too low and not typically used as a reference point for uterine fundal assessment. Midline (B) is vague and does not provide a specific anatomical landmark. Sides of the abdomen (D) do not give a standardized starting point for measuring the uterine fundus, leading to potential variability in assessment.

Correct Answer: D

Rationale: The correct answer is D: Temporal lobe. Memory and learning are primarily associated with the temporal lobe, specifically the hippocampus. Damage to this area due to stroke can lead to memory loss and impaired learning capacity. Frontal lobe (A) is involved in decision-making and problem-solving. Parietal lobe (B) is responsible for sensory processing. Occipital lobe (C) is related to visual processing. Therefore, the temporal lobe is the most likely site of brain damage in this scenario based on the symptoms presented.

D: Hematologic conditions may affect bone health, but they are not typically the primary cause of increased fracture risk in patients.

Correct Answer: A

Rationale: The correct answer is A: Ceftriaxone and azithromycin. Ceftriaxone covers Streptococcus pneumoniae, the most common pathogen in CAP, while azithromycin covers atypical pathogens like Mycoplasma pneumoniae. Vancomycin and piperacillin/tazobactam (choice B) are not first-line treatments for CAP. Ampicillin-sulbactam and levofloxacin (choice C) cover some pathogens but not as comprehensively as ceftriaxone and azithromycin. Clindamycin and cefepime (choice D) do not provide adequate coverage for typical CAP pathogens.
