Fundamentals of Nursing Nursing Process Questions

Correct Answer: B

Rationale: The correct answer is B: Fluorouracil (5-fluorouracil, 5 FU [Fluoroplex]). Fluorouracil is commonly used in chemotherapy for liver cancer to inhibit cancer cell growth. It is a pyrimidine analog that interferes with DNA synthesis. Fluoxymesterone (A) is an androgen used in hormone replacement therapy, not in liver cancer treatment. Tamoxifen (C) is an antiestrogen used in breast cancer treatment, not liver cancer. Megestrol (D) is a progestin used in hormone therapy for breast cancer and endometrial cancer, not liver cancer. Therefore, the correct choice is B as it directly targets cancer cell growth in liver cancer treatment.

Correct Answer: D

Rationale: The correct answer is D: Evaluation. After implementing nursing interventions based on priority diagnoses, the nurse must evaluate the effectiveness of these interventions to determine if the desired outcomes have been achieved. Evaluation is crucial to assess the progress, make necessary modifications, and ensure the effectiveness of the care provided. Assessment (A) is already completed before interventions are carried out. Planning (B) involves developing a care plan based on assessment findings. Implementation (C) is the actual carrying out of the interventions. Therefore, the next step after implementing nursing interventions is to evaluate their effectiveness.

Correct Answer: B

Rationale: The correct answer is B: All women over age 40 should have an annual mammogram. The American Cancer Society recommends annual mammograms starting at age 40 for women with an average risk of breast cancer. This is based on evidence showing that regular mammograms starting at age 40 help in early detection and improve outcomes. Choice A is incorrect because the recommended age is 40, not 30. Choice C is incorrect as it focuses only on family history, while screening guidelines are based on overall risk factors. Choice D is incorrect because feeling at risk alone is not a sufficient indication for annual mammograms without considering other risk factors.

Correct Answer: C

Rationale: The correct answer is C (5 years) because ALS is a progressive and fatal neurodegenerative disease. The median life expectancy for most ALS patients is around 3-5 years from the onset of symptoms. Choice A (3 years) is too short for 50% of patients. Choice B (10 years) and Choice D (20 years) are longer than the typical life expectancy for ALS patients, making them incorrect. The progression of ALS varies among individuals, but statistically, 50% of patients would be expected to live around 5 years after diagnosis.

Correct Answer: C

Rationale: The correct answer is C: 5% dextrose in 0.9% NaCl. This solution is hypertonic because it has a higher osmolarity compared to the other choices. The presence of dextrose and NaCl in this solution increases its solute concentration, causing water to move out of the cells by osmosis. Normal saline (A) and 0.45% NaCl (B) are isotonic solutions, meaning they have the same osmolarity as body fluids. 0.225% NaCl (D) is a hypotonic solution with lower osmolarity than body fluids.
