Correct Answer: C

Rationale: The correct statement is that Guillain-Barre Syndrome causes muscle weakness in the legs. This muscle weakness typically starts in the legs and can progress to the upper body. Choice A is incorrect as while most cases do improve, the recovery time can vary. Choice B is incorrect as Guillain-Barre Syndrome primarily affects muscle weakness rather than sensation. Choice D is incorrect as severe cases of Guillain-Barre Syndrome can lead to respiratory muscle weakness, impacting breathing.

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: Encouraging the client to identify their own strengths is empowering and helps build self-awareness and self-confidence. This strategy promotes autonomy and self-efficacy, enabling the client to recognize and utilize their personal strengths effectively. Option B, promoting the client's active external thinking, is vague and not directly related to recognizing personal strengths. Option C, listening to the client and providing advice as needed, focuses more on the nurse's role rather than empowering the client to recognize their strengths independently. Option D, assisting the client in maintaining an external locus of control, goes against the goal of helping the client recognize and utilize their internal strengths.

Correct Answer: D

Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy may have other potential benefits, such as improving mood or helping with seasonal affective disorders, the main focus and effectiveness of light therapy are commonly linked to regulating sleep patterns. Therefore, the correct answer is 'Working with sleep patterns.' Choices A, B, and C are incorrect as light therapy is not primarily used for overcoming weight problems, helping with allergies, or solely as an alternative medical treatment.

Correct Answer: C

Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding. Pernicious anemia results from vitamin B12 deficiency due to a lack of intrinsic factor, leading to faulty absorption from the gastrointestinal tract. While pernicious anemia can lead to other health issues, bleeding tendencies are not a primary concern. Metastatic liver cancer (choice A) can cause liver dysfunction leading to decreased synthesis of clotting factors, increasing the risk of bleeding. Gram-negative septicemia (choice B) can lead to disseminated intravascular coagulation (DIC) causing excessive bleeding. Iron-deficiency anemia (choice D) can result in microcytic hypochromic red blood cells, which can impair oxygen transport and lead to tissue hypoxia, but it is not directly associated with a significant potential for bleeding.
