A nurse is reviewing the laboratory findings for a client who developed fat embolism syndrome (FES) following a fracture. Which of the following laboratory findings should the nurse expect?
- A. Increased serum calcium level
- B. Decreased serum calcium level
- C. Increased white blood cell count
- D. Decreased platelet count
Correct Answer: B
Rationale: The correct answer is B: Decreased serum calcium level. In fat embolism syndrome (FES), fat globules enter the bloodstream, leading to blockages in small blood vessels. This can cause a decrease in serum calcium due to the formation of fat emboli in the pulmonary circulation, leading to hypoxia and subsequent release of inflammatory mediators that can affect calcium levels. The other choices are incorrect because in FES, there is no direct effect on serum calcium levels. Increased serum calcium levels (choice A) are not expected in FES. While increased white blood cell count (choice C) and decreased platelet count (choice D) can occur in response to inflammation or infection associated with FES, they are not specific laboratory findings for FES.

A client reports skin dryness, redness, and scaling after radiation. What should the nurse advise?
- A. Apply hydrating lotions.
- B. Scrub the area vigorously.
- C. Cover the area with adhesive bandages.
- D. Avoid moisturizing the skin.
Correct Answer: A
Rationale: The correct answer is A: Apply hydrating lotions. After radiation, skin can become dry and irritated. Hydrating lotions help to moisturize the skin and reduce dryness, redness, and scaling. They provide a protective barrier and promote skin healing. Advising the client to apply hydrating lotions is essential in maintaining skin integrity post-radiation.
Choice B: Scrubbing the area vigorously can further damage the skin and exacerbate irritation.
Choice C: Covering the area with adhesive bandages can trap moisture and lead to skin maceration.
Choice D: Avoiding moisturizing the skin can worsen dryness and discomfort.
A female middle adult client tells a nurse that she tested positive for a mutant BRCA1 gene. The nurse should recognize that the client is at an increased risk for which of the following situations?
- A. Developing breast cancer
- B. Developing ovarian cancer
- C. Developing uterine cancer
- D. Developing cervical cancer
Correct Answer: A
Rationale: The correct answer is A: Developing breast cancer. The BRCA1 gene mutation is associated with an increased risk of breast cancer in women. The mutation affects the body's ability to repair damaged DNA, leading to a higher likelihood of developing breast cancer. This risk is significantly higher in women with the mutant BRCA1 gene compared to those without it. Choices B, C, and D are incorrect because the BRCA1 gene mutation is not specifically linked to an increased risk of ovarian, uterine, or cervical cancer. Therefore, the client should be counseled and monitored closely for early detection and prevention of breast cancer.
A nurse is instructing a client how to decrease the nausea associated with chemotherapy and radiation. Which of the following statements indicates an understanding of the teaching?
- A. I will eat food that are served at room temperature.
- B. I will avoid drinking liquids with meals.
- C. I will eat spicy foods to improve appetite.
- D. I will drink hot liquids to settle my stomach.
Correct Answer: A
Rationale: The correct answer is A: "I will eat food that are served at room temperature." This is correct because consuming foods at room temperature helps reduce nausea associated with chemotherapy and radiation. Cold foods can worsen nausea, while hot foods can trigger vomiting. Avoiding extreme temperatures can help alleviate nausea.
Choice B is incorrect because avoiding liquids with meals can lead to dehydration and worsen nausea. Choice C is incorrect because spicy foods can exacerbate nausea rather than improve appetite. Choice D is incorrect because drinking hot liquids can aggravate nausea.
A nurse in an emergency department is caring for a client who reports substernal chest pain and dyspnea. The client is vomiting and is diaphoretic. Which of the following laboratory tests are used to diagnose a myocardial infarction? (Select all that apply.)
- A. Troponin I, Troponin T, CPK, Myoglobin
- B. Plasma low-density lipoproteins
- C. White blood cell count
- D. Blood glucose level
Correct Answer: A
Rationale: The correct answer is A. Troponin I, Troponin T, CPK, and Myoglobin are all specific laboratory tests used to diagnose a myocardial infarction. Troponin I and T are cardiac biomarkers released into the bloodstream following myocardial cell injury. Creatine phosphokinase (CPK) is an enzyme found in high concentrations in the heart muscle, and elevated levels indicate myocardial damage. Myoglobin is a protein released from damaged muscle cells, including cardiac muscle. These tests provide crucial information to confirm the diagnosis of a myocardial infarction.
Plasma low-density lipoproteins are not specific for diagnosing a myocardial infarction. White blood cell count is not typically used for diagnosing a myocardial infarction, although it may be elevated in response to inflammation associated with heart damage. Blood glucose level is not specific for diagnosing a myocardial infarction and
A nurse is teaching a client about the causes of osteoporosis. The nurse should include which of the following types of medication therapy as a risk factor for osteoporosis?
- A. Thyroid hormones
- B. Antihypertensives
- C. Steroids
- D. Insulin
Correct Answer: C
Rationale: The correct answer is C: Steroids. Steroids, specifically glucocorticoids, are known to increase the risk of osteoporosis by decreasing bone formation and increasing bone resorption. Long-term use of steroids can lead to bone loss, making individuals more susceptible to fractures. Thyroid hormones (A) do not directly cause osteoporosis. Antihypertensives (B) and insulin (D) are not associated with increased risk of osteoporosis.
