Rationale: Research at work is an example of self-directed learning activity because it involves taking the initiative to seek out information, learn new skills, and solve problems independently within a workplace setting. This type of learning requires self-motivation, self-discipline, and autonomy to set goals, gather resources, and develop knowledge or expertise in a specific area. Individuals engage in research at work to enhance their professional growth, expand their skill set, or address challenges encountered in their job responsibilities. It is a proactive approach to learning where individuals take charge of their own development and continuously strive to improve their performance.

Rationale: The correct way to apply anti-scabies lotion is to cover all skin areas, not just the affected areas or red areas.

Rationale: The most likely causative agent in this scenario is Plasmodium falciparum, which is the parasite that causes malaria. The symptoms of fever, chills, headache, and myalgia following a camping trip are highly suggestive of malaria, especially if the patient has thrombocytopenia and leukopenia. Plasmodium falciparum is known to cause severe malaria with complications such as thrombocytopenia and leukopenia. The other options, Trypanosoma cruzi, Borrelia burgdorferi, and Leishmania donovani, do not typically present with all of the symptoms described and are not associated with the laboratory findings of thrombocytopenia and leukopenia.

Correct Answer: A

Rationale: The diagnostic examination for osteoporosis typically involves measuring bone density. This is usually done through a dual-energy x-ray absorptiometry (DEXA) scan, which is considered the gold standard for assessing bone density. Osteoporosis is characterized by decreased bone mass and deterioration of bone tissue, leading to increased bone fragility and risk of fractures. Measuring bone density helps in diagnosing osteoporosis by identifying areas of low bone density, assessing the risk of fractures, and monitoring the effectiveness of treatment. Weight, blood volume, and height are not directly used as primary indicators for diagnosing osteoporosis.

Correct Answer: B

Rationale: Sunken fontanels are one of the earliest signs of dehydration in infants. Fontanels are soft spots on an infant's head where the skull bones have not yet fused together. If a baby's fontanel appears sunken, it indicates that the baby is likely dehydrated. This occurs because when there is a lack of fluid in the body, the soft spots on the head will appear depressed or sunken. It is crucial for Nurse Juvy to closely monitor the fontanels of Baby Sharon, as identifying dehydration early is essential for prompt intervention and preventing complications.
