Correct Answer: B

Rationale: The correct answer is B: Initiate non-invasive positive pressure ventilation (NIPPV) for respiratory support. In acute exacerbations of COPD, NIPPV helps improve ventilation and oxygenation, reducing the work of breathing and preventing the need for intubation. This intervention is a priority as it can rapidly stabilize the patient's respiratory status. A: Administering bronchodilator medications is important in COPD management, but in severe exacerbations, NIPPV takes precedence. C: Arterial blood gas analysis is important for assessing oxygenation and ventilation status, but it does not directly address the acute respiratory distress. D: Chest physiotherapy can help with airway clearance in COPD, but in acute exacerbations, respiratory support with NIPPV is more urgent.

Correct Answer: A

Rationale: The correct answer is A: Scabies. This presentation is classic for scabies infestation caused by the Sarcoptes scabiei mite. The intensely pruritic linear burrows are pathognomonic. Close contact with an individual with scabies increases the likelihood of transmission. The other choices, B: Pediculosis, C: Tinea corporis, and D: Contact dermatitis, do not typically present with linear burrows on the hands and wrists. Pediculosis presents with lice infestation, Tinea corporis with circular lesions, and contact dermatitis with erythema and edema.

Correct Answer: A

Rationale: The correct answer is A because it includes all the major endocrine glands: pituitary, thyroid, parathyroid, adrenals, pancreatic islets, and hypothalamus. The pituitary gland is known as the "master gland" as it controls other endocrine glands. The thyroid gland regulates metabolism, while the parathyroid glands regulate calcium levels. The adrenal glands produce hormones involved in stress response. Pancreatic islets produce insulin and glucagon. The hypothalamus plays a key role in hormone regulation. Choice B is incorrect because it includes ovaries and testes, which are not endocrine glands. Choice C is incorrect because it omits the hypothalamus. Choice D is incorrect because it includes ovaries and testes which are not endocrine glands.

Correct Answer: C

Rationale: Step 1: The Universal Health Care law aims to provide all Filipinos access to quality and affordable healthcare services, including medicines. Step 2: This law covers a broader scope compared to the other choices. Step 3: The Local Government Code focuses on local governance, not specifically on healthcare. Step 4: Primary Health Care is a concept rather than a specific law targeting affordable medicines. Step 5: The Generic Drug Act promotes the use of generic drugs but does not guarantee affordability for all Filipinos.

Correct Answer: A

Rationale: Correct Answer: A - sterile clamps Rationale: 1. **Immediate action**: Sterile clamps are essential to clamp the chest tube to prevent air from entering the pleural space. 2. **Prevent lung collapse**: Clamping the tube will prevent lung collapse and maintain positive pressure in the pleural space. 3. **Buy time**: By clamping the tube, you buy time to properly reattach the tube or secure it with a new connection. 4. **Safety**: Sterile clamps are a quick and effective solution to prevent a potentially life-threatening situation. Summary of other choices: B: Sterile dressing - Not the first priority as the immediate concern is preventing air from entering the pleural space. C: Another chest tube - Not necessary initially as clamping can buy time to reattach the disconnected tube. D: A bottle of sterile water - Not needed for emergency management of a disconnected chest tube.
