The nurse working in the bloodmobile is screening clients to determine if they qualify for blood donation of whole blood. Besides asking for identification and age, which questions should the nurse ask during the screening interview?
- A. “If you have a tattoo, on what date did you receive the tattoo?”
- B. “Have you had any close contact with anyone with HIV or hepatitis?”
- C. “If you smoke, when was the last time you smoked tobacco products?”
- D. “When were you last immunized for rubella, mumps, or varicella?”
- E. “Did you receive blood products anywhere outside of the United States?”
Correct Answer: A, B, D, E
Rationale: Persons ineligible to donate blood include those with a history of a recent tattoo. B. Persons ineligible to donate blood include those who’ve had close contact with a person with HIV or hepatitis. C. Persons who smoke tobacco products may donate blood unless they have a recent history of asthma. D. Persons ineligible to donate blood include those immunized for rubella, mumps, or varicella within the last month. E. Persons ineligible to donate blood include those receiving transfusions in the United Kingdom, Gibraltar, or the Falkland Islands because of the increased likelihood of transmitting Creutzfeldt-Jakob disease.

The client admitted with full-thickness burns may be developing DIC. Which signs/symptoms would support the diagnosis of DIC?
- A. Oozing blood from the IV catheter site.
- B. Sudden onset of chest pain and frothy sputum.
- C. Foul-smelling, concentrated urine.
- D. A reddened, inflamed central line catheter site.
Correct Answer: A
Rationale: DIC causes uncontrolled bleeding; oozing from IV sites (A) is a hallmark. Chest pain/sputum (B) suggests PE, urine odor (C) is unrelated, and redness (D) indicates infection.
The nurse administers iron using the Z track technique. What is the primary reason for administering iron via Z track?
- A. To prevent adverse reactions
- B. To prevent staining of the skin
- C. To improve the absorption rate
- D. To increase the speed of onset of action
Correct Answer: B
Rationale: The Z track technique prevents iron from leaking into subcutaneous tissue, reducing skin staining.
A Schilling test has been ordered for a client suspected of having pernicious anemia. What is the nurse's primary responsibility in relation to this test?
- A. Collect the blood samples
- B. Collect a 24-hour urine sample
- C. Assist the client to x-ray
- D. Administer an enema
Correct Answer: B
Rationale: The Schilling test involves administering radioactive vitamin B12 orally and collecting a 24-hour urine sample to assess absorption, indicating the nurse's primary responsibility.
The client who was recently admitted with gastric cancer appears pale and weak and states feeling fatigued. In reviewing the client’s laboratory results, which component of the CBC should the nurse most associate with the client’s gastric cancer and identify as the causative factor for the fatigue?
- A. White blood cell 12,200/mm3
- B. Hemoglobin 7.9 g/dL
- C. Serum protein 5.9 g/dL
- D. Blood urea nitrogen 22 mg/dL
Correct Answer: B
Rationale: A. The elevation in the WBC (normal is 4500–10,000/mm3 or microL) is concerning because it could indicate an infection, but the elevation would not necessarily be related to the gastric cancer. B. The presenting symptoms are indicative of anemia, which is common in gastric cancer due to chronic blood loss, or as a result of pernicious anemia (due to loss of intrinsic factor). The low Hgb (normal is 12–15 g/dL) may be the causative factor for the fatigue. C. The serum protein is slightly low (normal is 6.0–8.0 g/dL) and could be indicative of nutritional problems associated with the gastric cancer, but it is not specific to the signs and symptoms described in the question, and it is not part of a CBC. D. The BUN (normal is 5–25 mg/dL) is within normal parameters and is measuring kidney function or hydration status. It is not part of the CBC.
The nurse receives orders after notifying an HCP about the client who has tachycardia, diaphoresis, and an elevated temperature after treatments for ALL. Which order should be the nurse’s priority?
- A. Portable chest x-ray in the client’s room
- B. Urine culture, and blood cultures x 2
- C. Vancomycin 500 mg IV q6h
- D. Filgrastim 0.3 mg subcut daily
Correct Answer: B
Rationale: A. The results of the portable CXR will help determine if the cause is a respiratory infection. It will not change the treatment. B. Urine and blood cultures are priority; these should be obtained before antibiotics are administered. C. National recommendations are to administer broad-spectrum antibiotics such as vancomycin (Vancocin) within 1 hour of a suspected infection diagnosis. The antibiotics may be changed after culture and sensitivity reports are available (usually 24 to 48 hours). D. It takes 4 days for filgrastim (Neupogen) to return the neutrophil count to baseline, so this is not priority. Filgrastim should not be given within 24 hours of cytotoxic chemotherapy.
