Nursing Process Practice Questions Quizlet

Correct Answer: D

Rationale: Step 1: Hypernatremia is defined by elevated serum sodium levels (>145mEq/L). Step 2: Serum osmolality of 245mOsm/kg is high, consistent with hypernatremia. Step 3: Urine specific gravity below 1.003 indicates dilute urine, a common finding in hypernatremia. Step 4: The combination of elevated serum sodium, high serum osmolality, and low urine specific gravity confirms hypernatremia. Summary: A: Incorrect, as high serum osmolality (not 245mOsm/kg) is associated with hypernatremia. B: Incorrect, as low urine specific gravity (not below 1.003) is seen in hypernatremia. C: Incorrect, as serum sodium needs to be >145mEq/L to indicate hypernatremia.

Correct Answer: C

Rationale: The correct answer is C. Aling Maria is admitted for myxedema, which is severe hypothyroidism. Symptoms of hypothyroidism include lethargy, weight gain, slow speech, and decreased respiratory rate. Bradycardia, weight loss, heart failure, and diarrhea are not typical symptoms of myxedema. Tachycardia, constipation, and exopthalmus are more commonly associated with hyperthyroidism. Hypothermia, weight loss, and increased respiratory rate are not consistent with myxedema. Thus, choice C is the most appropriate initial assessment for Aling Maria.

Correct Answer: C

Rationale: The correct answer is C: "Divided doses produce greater cytotoxic effects on the diseased cells." Dividing the doses of the antimetabolite allows for more consistent levels of the drug in the bloodstream, ensuring sustained exposure to the cancer cells. This continuous exposure enhances the drug's cytotoxic effects, increasing its efficacy in targeting and destroying the diseased cells. Options A and B provide vague or incorrect information, while option D is misleading as antimetabolites do not prevent cell division, but rather disrupt DNA synthesis.

Correct Answer: C

Rationale: After a transsphenoidal adenohypophysectomy, hormone replacement therapy is needed due to the removal of the pituitary gland. This surgery is typically done to treat pituitary carcinoma, making choice C the correct answer. Pituitary carcinoma is a type of cancer that affects the pituitary gland. Choices A, B, and D are incorrect because they do not involve the pituitary gland. Esophageal carcinoma affects the esophagus, laryngeal carcinoma affects the larynx, and colorectal carcinoma affects the colon and rectum. Therefore, the correct choice, C, is the only one related to the pituitary gland and the procedure described.

Correct Answer: C

Rationale: The correct answer is C: Amount and color of sinus drainage. Assessing the amount and color of sinus drainage is crucial in evaluating the effectiveness of nursing interventions for sinusitis discomfort as it indicates the presence of infection or inflammation. Changes in color or amount can signify improvement or worsening of the condition. WBC count (A) may indicate infection but doesn't directly reflect sinusitis discomfort. Capillary refill (B) assesses circulation, not sinusitis. Comfort level (D) is subjective and can vary among individuals, making it less reliable for assessing the effectiveness of interventions.
