1. When preparing a client for platelet pheresis in the blood bank, which information is most significant to obtain during the history assessment?

• A. Allergies to shellfish
• B. Date of last platelet donation
• C. Time of last oral intake
• D. Blood type

Correct answer: B

Rationale: The most significant information to gather when a client is scheduled for platelet pheresis is the date of their last platelet donation. Platelet donors can typically have their platelets apheresed as frequently as every 14 days. Knowing the date of the last donation helps ensure the client is eligible for the procedure without risking any adverse effects from frequent donations. Allergies to shellfish may be important for other procedures where anticoagulants containing heparin are used, but it is not directly related to platelet pheresis. The time of the last oral intake is more crucial for procedures requiring sedation or anesthesia. Blood type is significant for blood transfusions but is not the primary concern for platelet pheresis.

2. Which of the following microorganisms is easily transmitted from client to client on the hands of healthcare workers?

• A. mycobacterium tuberculosis
• B. clostridium tetani
• C. staphylococcus aureus
• D. human immunodeficiency virus

Correct answer: C

Rationale: The correct answer is staphylococcus aureus. Staphylococcus aureus microorganisms are ubiquitous and easily transmitted by healthcare workers who fail to conduct routine hand washing between clients. Staphylococcus aureus can reside on the skin and be transferred from one client to another if proper hand hygiene is not practiced. Mycobacterium tuberculosis is mainly transmitted through the airborne route, clostridium tetani is usually acquired through exposure to soil or dirt contaminated with tetanus spores, and human immunodeficiency virus is not easily transmitted through casual contact or on the hands of healthcare workers.

3. A client begins a regimen of chemotherapy. Her platelet count falls to 98,000. Which action is least likely to increase the risk of hemorrhage?

• A. Test all excreta for occult blood.
• B. Use a soft toothbrush or foam cleaner for oral hygiene.
• C. Implement reverse isolation.
• D. Avoid IM injections.

Correct answer: C

Rationale: The correct answer is to implement reverse isolation. Reverse isolation is a protective measure used to protect patients from infections, not to affect the risk of hemorrhage. Testing all excreta for occult blood (Choice A) is important to monitor for signs of internal bleeding. Using a soft toothbrush or foam cleaner for oral hygiene (Choice B) is recommended to prevent gum bleeding. Avoiding IM injections (Choice D) is crucial to reduce the risk of bleeding in a client with a low platelet count. Therefore, among the given options, implementing reverse isolation is the least likely to increase the risk of hemorrhage.

4. What is the most common cause of acute renal failure?

• A. Shock
• B. Nephrotoxic drugs
• C. Enlarged prostate
• D. Diabetes

Correct answer: A

Rationale: The most common cause of acute renal failure is shock. In cases of shock, such as hypovolemic shock where there is low blood volume, the kidneys receive inadequate blood flow leading to acute renal failure. This can result in the kidneys starting to die within 20 minutes of low pressure. While nephrotoxic drugs can also cause acute renal failure, shock is more commonly associated with this condition. An enlarged prostate can lead to urinary retention but is not the most common cause of acute renal failure. Diabetes, on the other hand, can cause chronic kidney disease over time but is not typically the primary cause of acute renal failure.

5. What could be a possible cause for the symptoms experienced by the client in Question 28?

• A. iron deficiency
• B. folate deficiency
• C. peptic ulcer
• D. iron overload

Correct answer: A

Rationale: Given the client's symptoms of fatigue, shortness of breath, and lightheadedness, along with her gender and fad dieting, the most likely cause is iron deficiency. Iron deficiency commonly presents with these symptoms due to decreased oxygen-carrying capacity in the blood. Folate deficiency would typically present with different symptoms such as mouth sores and changes in skin, not fitting the client's presentation. Peptic ulcer would manifest with abdominal pain, not primarily with the symptoms described. Iron overload would present with symptoms such as joint pain and fatigue, which are not consistent with the client's presentation.
