Correct Answer: D

Rationale: The symptoms described - muscle weakness, fatigue, constipation, hyperpigmentation of the skin, low serum cortisol levels, and elevated ACTH levels - are classic findings in Addison's disease. Addison's disease is a primary adrenal insufficiency characterized by the insufficient production of cortisol and, to some extent, aldosterone. The low cortisol levels result in symptoms such as muscle weakness, fatigue, and skin hyperpigmentation due to increased levels of ACTH stimulating melanin production. In contrast, in conditions like hyperthyroidism, hypothyroidism, and diabetes mellitus, the symptoms and laboratory findings would not fully align with those described in the patient in this scenario.

Correct Answer: A

Rationale: Given the sudden-onset severe scrotal pain, swelling, and erythema, along with the physical examination findings of a tender, swollen, and high-riding testicle, the most likely diagnosis is testicular torsion. Testicular torsion occurs when the spermatic cord twists, leading to compromised blood flow to the testicle, causing ischemia and severe pain. It is considered a surgical emergency that requires prompt diagnosis and intervention to salvage the affected testicle. Prompt surgical detorsion is necessary to prevent irreversible testicular damage. While epididymitis, testicular trauma, and testicular tumors can also present with scrotal pain and swelling, the presence of a high-riding testicle in this context is highly suggestive of testicular torsion.

Correct Answer: C

Rationale: The best thing for Nurse Kayla to do for the patient is to encourage her to ambulate and to void. In this scenario, the fundus being firm, above the umbilicus, and deviated to the right indicates uterine atony with a full bladder. This finding is suggestive of a distended bladder pushing the uterus upwards and to the right. Encouraging the patient to ambulate helps promote uterine contractions, which can aid in the firming up of the uterus. Additionally, emptying the bladder will help the uterus to contract and return to its midline position. This intervention is non-invasive and promotes normal postpartum recovery without the need for medication or excessive manipulation.

Correct Answer: A

Rationale: The patient's symptoms of fever, chills, headache, and myalgia after returning from sub-Saharan Africa are consistent with malaria. Intraerythrocytic ring forms and trophozoites observed on blood smear examination are characteristic of Plasmodium species, particularly Plasmodium falciparum, which is the most common and deadliest species causing malaria in sub-Saharan Africa. Plasmodium falciparum can lead to severe complications, such as cerebral malaria, if not promptly treated. Trypanosoma cruzi causes Chagas disease, not malaria. Borrelia burgdorferi is responsible for Lyme disease, which typically presents with a different set of symptoms like erythema migrans rash. Leishmania donovani causes visceral leishmaniasis, not malaria.

Correct Answer: B

Rationale: In the universal health law, the government agencies that are considered as "key players" in its implementation are the Department of Health (DOH), Local Government Units (LGUs), and the Philippine Health Insurance Corporation (PhilHealth).
