A client has a bone marrow biopsy done. Which nursing intervention is the priority post-procedure?

Correct Answer: A

Rationale: The correct answer is A. Applying pressure to the biopsy site is the priority post-procedure to prevent bleeding and ensure hemostasis. Inspecting the site for ecchymoses can be done after ensuring hemostasis. Sending the biopsy specimens to the laboratory is important but not as immediate as ensuring the client's safety. Teaching the client about avoiding vigorous activity is important for overall recovery but not as immediate as preventing bleeding post-procedure.

Correct Answer: B

Rationale: The correct answer is B: Platelet (thrombocyte) count. Platelet count typically remains relatively stable with age, so a decreased value in a 76-year-old client would be concerning. Hemoglobin (Hgb) level can decrease with age due to factors like nutritional deficiencies. Red blood cell (RBC) count tends to decrease with age as well. White blood cell (WBC) response can vary with age and immune system activity. Therefore, the decreased platelet count is the most concerning as it is not typically age-related, making it the correct answer.

Correct Answer: B

Rationale: The correct answer is B because the number of red blood cells varies with gender, age, and general health. This response is accurate as it acknowledges the variability in red blood cell counts among individuals. Choice A is incorrect as it provides a definitive answer without considering the factors influencing red blood cell count. Choice C is incorrect because it gives a blanket statement that all people have the same number of red blood cells, which is not true. Choice D is incorrect as it incorrectly links anemia directly to the number of red blood cells without considering the broader context of red blood cell variability.

Correct Answer: B

Rationale: The correct answer is B: No neurological symptoms in folic acid. Vitamin B12 and folic acid deficiencies both can lead to megaloblastic anemia and similar hematological symptoms. However, vitamin B12 deficiency can also cause neurological symptoms due to its role in nerve function, which folic acid deficiency does not. Glossitis (choice A) can be a symptom of both deficiencies. Muscle wasting (choice C) is not a common symptom of either deficiency. Dizziness (choice D) is a nonspecific symptom and can occur with various vitamin deficiencies, not specific to vitamin B12 or folic acid.

Correct Answer: B

Rationale: The correct answer is B: FALSE. Angular stomatitis/cheilosis is not a symptom specific to vitamin B12 deficiency. This condition is more commonly associated with deficiencies in iron, riboflavin, and niacin. Vitamin B12 deficiency typically presents with symptoms such as fatigue, weakness, pale skin, and neurological issues. Therefore, options A and C are incorrect as angular stomatitis/cheilosis is not sometimes or always a symptom of vitamin B12 deficiency. Option D is also incorrect as this condition can occur in individuals of all ages, not just children.
