Which of the following is a characteristic feature of Crohn's disease?
Formation of fistulas and abscesses.
Symptoms confined to the large intestine.
Improvement with the use of antibiotics.
Presence of rectal bleeding.
The Correct Answer is A
Choice A rationale
Formation of fistulas (abnormal connections between organs) and abscesses (collections of pus) are characteristic complications of Crohn's disease. The transmural inflammation in Crohn's disease can penetrate through the bowel wall, leading to these developments.
Choice B rationale
Crohn's disease can affect any part of the gastrointestinal tract from the mouth to the anus, although it most commonly involves the ileum and colon. Symptoms are not confined to the large intestine. Ulcerative colitis, another inflammatory bowel disease, primarily affects the colon.
Choice C rationale
While antibiotics may be used to treat secondary infections or complications of Crohn's disease, they are not a primary treatment for the underlying inflammatory process and do not typically lead to improvement of the disease itself. Crohn's disease is a chronic inflammatory condition that requires immunomodulatory or anti-inflammatory medications.
Choice D rationale
Rectal bleeding is more commonly associated with ulcerative colitis, where the inflammation is typically limited to the mucosal layer of the colon and rectum, leading to ulceration and bleeding. While some bleeding can occur in Crohn's disease, it is generally less prominent than in ulcerative colitis.

Correct Answer is B
Explanation
Choice A rationale
While the partner's intention may be good, allowing someone other than the client to administer PCA medication bypasses the safety mechanisms built into the pump and disregards the client's ability to self-titrate based on their pain level. This could lead to over-sedation and respiratory depression.
Choice B rationale
Patient-controlled analgesia is designed to allow clients to manage their own pain by self-administering medication within prescribed limits. The client is the best judge of their pain intensity and medication needs. Allowing the partner to push the button undermines this principle of patient autonomy and safety.
Choice C rationale
The nurse should not administer PCA medication based on a third party's assessment of the client's needs. This still circumvents the client's control and the safety features of the pump. The nurse's role is to assess the client directly and educate the client and family on proper PCA use.
Choice D rationale
While it's important to understand the partner's reasoning, the immediate concern is the inappropriate administration of medication. Addressing the partner's actions directly and educating them on the proper use of the PCA pump is the priority.
Correct Answer is B
Explanation
Choice A rationale
Herpes simplex virus type 2 (HSV-2) is highly contagious through direct contact with the virus, which can be present on towels and other personal items. Sharing towels, even with family members, can facilitate the transmission of the virus, especially during active outbreaks.
Choice B rationale
Prior to the development of visible blisters, many individuals with HSV-2 experience prodromal symptoms such as itching, tingling, or burning at the site where the lesions will eventually appear. This indicates an understanding of the early signs of a recurrent outbreak.
Choice C rationale
Daily antiviral medication for HSV-2 is suppressive therapy, which helps to reduce the frequency, duration, and severity of outbreaks, as well as the risk of transmission. However, it does not entirely prevent the occurrence of sores in all individuals.
Choice D rationale
Even after the blisters rupture and begin to heal, the herpes simplex virus can still be present in the secretions and can potentially be transmitted to others through direct contact until the lesions are completely healed and the skin is intact.
