A patient with suspected community-acquired pneumonia (CAP) is empirically started on antibiotic therapy pending culture results. Which of the following antibiotic regimens provides appropriate coverage for typical bacterial pathogens commonly implicated in CAP?

Correct Answer: A

Rationale: The correct answer is A: Ceftriaxone and azithromycin. Ceftriaxone covers Streptococcus pneumoniae, the most common pathogen in CAP, while azithromycin covers atypical pathogens like Mycoplasma pneumoniae. Vancomycin and piperacillin/tazobactam (choice B) are not first-line treatments for CAP. Ampicillin-sulbactam and levofloxacin (choice C) cover some pathogens but not as comprehensively as ceftriaxone and azithromycin. Clindamycin and cefepime (choice D) do not provide adequate coverage for typical CAP pathogens.

Correct Answer: B

Rationale: The correct answer is B: Equity in services. Collaboration and teamwork in public health are crucial to ensure equal access to services for all populations, regardless of their background or socioeconomic status. By working together, public health professionals can identify disparities and implement strategies to address them, ultimately leading to improved equity in healthcare services. A: Staff performance - While collaboration and teamwork can positively impact staff performance, the primary focus in public health is on achieving equity in services for all individuals. C: Proper use of resources - Collaboration can help optimize resource allocation, but the main goal in public health is to ensure equitable access to services. D: Quality healthcare - While collaboration can enhance the quality of healthcare, the primary emphasis in public health is on promoting equity in services to address health disparities.

Correct Answer: C

Rationale: The correct answer is C: Cells die. In Alzheimer's disease, there is a progressive degeneration of brain cells, leading to cell death. This results in a loss of important brain functions such as memory, cognition, and eventually, bodily functions. The atrophy of the brain stem (choice A) is not a characteristic feature of Alzheimer's. Fluid buildup (choice B) is not a primary mechanism of the disease. Tissue swelling (choice D) is not typically associated with the progression of Alzheimer's; rather, there is a gradual loss of brain tissue due to cell death.

Correct Answer: B

Rationale: The correct answer is B: Lie on the affected area. This position would hinder drainage and increase pressure on the affected area. A: Tilt head to the side if sitting up, is correct as it promotes drainage. C: Putting pillows behind the head can also aid drainage. D: Lying on the non-affected ear can help reduce pressure on the affected side.

Correct Answer: A

Rationale: The correct answer is A because obtaining the client's own consent is the first step in ensuring the client's autonomy and right to make decisions about their own care. This is in line with ethical principles of informed consent. Choices B, C, and D are incorrect because consent should come directly from the client, not from a spouse, family member, or social worker. Choice B violates the principle of individual autonomy, choice C is not the priority before admission, and choice D is not the appropriate person to provide consent.

Correct Answer: B

Rationale: The correct answer is B: Bright red and spurts with the heartbeat. This type of bleeding indicates arterial bleeding, which is oxygen-rich blood coming directly from the arteries. Arterial bleeding is bright red in color due to the high oxygen content and spurts with the heartbeat as it is under higher pressure. This rapid spurting is characteristic of arterial bleeding and requires immediate attention to control the bleeding source. Choices A, C, and D are incorrect because they describe characteristics of venous bleeding, not arterial bleeding. Venous bleeding is dark in color, flows slowly, and generally oozes as it is oxygen-depleted blood returning to the heart. Therefore, the correct answer is B based on the specific characteristics of arterial bleeding.

Correct Answer: B

Rationale: The primary goal of CPR is to restore spontaneous circulation and oxygenation to the body to maintain vital organ function. By performing chest compressions and rescue breaths, CPR aims to circulate oxygenated blood to the brain and other vital organs. This is crucial to prevent brain damage and increase the chances of survival. The other choices are incorrect because CPR does not address the underlying cause of cardiac arrest (A), provide pain relief (C), or prevent further complications such as organ failure (D). The immediate focus in a cardiac arrest situation is to maintain blood flow and oxygen delivery to vital organs until advanced medical care can be provided.

Correct Answer: D

Rationale: The correct answer is D: Professional Regulatory Board of Nursing. This board is specifically tasked with regulating the practice of the nursing profession, ensuring that nurses adhere to ethical and professional standards. The Department of Health (A) focuses on public health policies, not individual professional regulation. The Professional Regulation Commission (B) oversees various professions but does not specialize in nursing. The Civil Service Commission (C) deals with civil service matters, not professional nursing regulation. Therefore, the Professional Regulatory Board of Nursing is the most appropriate choice for regulating the nursing profession.

Correct Answer: C

Rationale: The correct answer is C: Notify the anesthesia provider for further assessment. This is the most appropriate action because an anesthesia provider is trained to assess and manage changes in blood pressure during surgery. Administering antihypertensive medication (A) without proper assessment can be dangerous. Documenting the readings (B) is important but not the immediate action. Continuing to monitor closely (D) is necessary but notifying the anesthesia provider for further assessment should be the priority.
