Adult Health Nursing Answer Key

Correct Answer: A

Rationale: The presentation described in the question is classic for basal cell carcinoma (BCC). BCC typically presents as multiple, flesh-colored, papular lesions with a central dell (resembling a pearl-like appearance) on sun-exposed areas such as the face and trunk. These lesions are known to bleed easily upon minor trauma and tend to increase in number over time. BCC is the most common type of skin cancer, often triggered by sun exposure. On the other hand, seborrheic keratosis (choice C) presents as benign, pigmented, stuck-on, waxy, or warty lesions with a rough surface, true bumpy appearance. Squamous cell carcinoma (choice B) usually presents as a scaly, erythematous, rapidly growing nodule, ulcer, or plaque. Actinic keratosis (choice D) presents as rough, scaly patches on sun-exposed areas that can progress to

Correct Answer: A

Rationale: The patient requiring a dressing change of post-caesarian surgery should be assigned to the midwife because this task involves specialized knowledge and skills related to wound care and post-operative care. Performing a dressing change for a post-caesarian surgery patient requires expertise to ensure proper hygiene, wound healing, and prevention of post-operative complications. This task goes beyond the scope of practice for a nursing assistant and should be done by a healthcare professional with higher qualifications and training, such as a midwife.

Correct Answer: B

Rationale: The stomach is the organ responsible for the mechanical and chemical digestion of food. When food enters the stomach, it is mixed with stomach acid and enzymes to break down the food into smaller particles. This process helps prepare the food for further digestion and absorption of nutrients. The stomach also plays a key role in the absorption of some nutrients, such as certain vitamins and minerals. Additionally, the stomach's muscular contractions help mix the food with digestive enzymes and propel the partially digested food into the small intestine for further processing and absorption. The liver, pancreas, and large intestine have vital functions in the digestive system, but the stomach is the primary organ responsible for the initial digestion and absorption of nutrients.

Correct Answer: D

Rationale: The best time for an incontinent patient to take diuretics is at bedtime. This timing allows for increased urine production during the night, consequently reducing the need for frequent toileting during the day. By taking the diuretic at bedtime, the patient can manage their incontinence more effectively and have better rest without disruptions from frequent urination during the day.

Correct Answer: C

Rationale: Cryptosporidium parvum is a parasite commonly found in contaminated water sources such as streams or lakes. It causes an infection called cryptosporidiosis, which often presents with symptoms like watery diarrhea, abdominal cramps, and nausea. The oocysts of Cryptosporidium parvum can be identified in stool samples, making it the likely culprit in this scenario. Giardia lamblia, another common waterborne parasite, can also cause similar symptoms but is characterized by trophozoites rather than oocysts in stool samples. Entamoeba histolytica is associated with amoebic dysentery and does not typically present with watery diarrhea. Cyclospora cayetanensis is another parasite causing gastrointestinal symptoms but is not as commonly associated with contaminated water sources as Cryptosporidium parvum.
