Correct Answer: D

Rationale: The correct answer is D, Broad opening. Nurse Rica should use this communication technique to encourage the patient to freely express themselves without leading or interrupting. This technique helps build rapport and trust, setting a positive tone for the conversation. A: Clarifying may be too direct and might make the patient feel pressured. B: Challenging can create defensiveness and hinder open communication. C: Restating may not be as effective in initiating a conversation as broad opening. In summary, broad opening allows for a more open and relaxed conversation, fostering a conducive environment for effective communication with the patient.

Correct Answer: D

Rationale: The correct answer is D because a journal article about a study using large, previously unpublished databases is a primary source as it presents original research findings firsthand. It contributes new knowledge to the field. A textbook (A) compiles existing information, not original research. A doctoral dissertation (B) critiques research but is not a primary source. A published commentary (C) interprets others' findings, making it a secondary source.

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: 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.

Correct Answer: A

Rationale: The correct answer is A because it includes all the major endocrine glands: pituitary, thyroid, parathyroid, adrenals, pancreatic islets, and hypothalamus. The pituitary gland is known as the "master gland" as it controls other endocrine glands. The thyroid gland regulates metabolism, while the parathyroid glands regulate calcium levels. The adrenal glands produce hormones involved in stress response. Pancreatic islets produce insulin and glucagon. The hypothalamus plays a key role in hormone regulation. Choice B is incorrect because it includes ovaries and testes, which are not endocrine glands. Choice C is incorrect because it omits the hypothalamus. Choice D is incorrect because it includes ovaries and testes which are not endocrine glands.
