A client has been diagnosed with Disseminated Intravascular Coagulation (DIC) and transferred to the medical intensive care unit (ICU) following an acute bleeding episode. In the ICU, continuous Heparin drip therapy is initiated. Which of the following assessment findings indicates a positive response to Heparin therapy?

Correct Answer: B

Rationale: Effective Heparin therapy should halt the process of intravascular coagulation, leading to increased availability of fibrinogen. Heparin interferes with thrombin-induced conversion of fibrinogen to fibrin. Therefore, an increased fibrinogen level indicates a positive response to Heparin therapy. While increased platelet count and decreased bleeding are positive outcomes, the specific indicator for Heparin therapy response is the increase in fibrinogen level. Decreased fibrin split products would also be a positive response, but an increase in fibrinogen directly reflects the impact of Heparin therapy.

Correct Answer: B

Rationale: The correct answer is B: alopecia. Chemotherapy drugs like vincristine and nitrogen mustard commonly cause hair loss (alopecia), which can significantly impact body image. While a Cushingoid appearance can be a side effect of long-term steroid use, it is not typically associated with the chemotherapy regimen mentioned. Temporary or permanent sterility can result from chemotherapy, affecting fertility but not directly contributing to altered body image. Pathologic fractures are not commonly linked to Hodgkin's disease or its treatment, unlike alopecia which is a well-known side effect.

Correct Answer: B

Rationale: Object permanence occurs when the infant learns that something or someone still exists even though they might not be able to see it or them. This typically develops between 9 and 10 months of age. The correct answer, 'The infant looks at the floor to find a toy that he was playing with and dropped,' demonstrates object permanence as the infant understands that the toy still exists even though it is temporarily out of sight. Choices A and C do not directly relate to object permanence as the behaviors described do not necessarily indicate an understanding of objects existing when out of sight. Choice D is incorrect as participating in a game of patty-cake does not involve demonstrating object permanence. Peek-a-boo is a more suitable example of a game that demonstrates object permanence, as the infant continues to look for the hidden face, understanding that it still exists even though temporarily unseen.

Correct Answer: B

Rationale: Acyclovir (Zovirax) is the drug of choice for herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), and varicella-zoster virus (VZV) infections. It works by inhibiting viral DNA replication. Acyclovir is excreted unchanged in the urine, so caution is needed in renal impairment. Choice A, HIV, is incorrect as acyclovir is not the drug of choice for HIV. Choice C, CMV, is incorrect as acyclovir is not the preferred treatment for cytomegalovirus (CMV) infections. Choice D, Influenza A viruses, is incorrect as acyclovir is not used to treat influenza viruses.

Correct Answer: A

Rationale: Erythropoietin is necessary for red blood cell (RBC) production, and in clients with renal failure who lack endogenous erythropoietin, exogenous erythropoietin is administered. However, for erythropoietin to effectively stimulate RBC production, adequate levels of iron, folic acid, and vitamin B12 are crucial. These nutrients are essential for RBC synthesis and maturation. Therefore, the correct answer is to give iron, folic acid, and B12 with erythropoietin. Choice B, an increase in protein in the diet, is not necessary for RBC production and may exacerbate uremia in clients with renal failure. Choices C and D, vitamins A and C, and an increase in calcium in the diet, respectively, are not directly related to RBC production and are not required to enhance the effectiveness of erythropoietin.
