You have arrived by the side of a cyanotic patient who is responsive to painful stimuli and exhibiting stridorous respirations. Which of the following would be most appropriate?

Correct Answer: A

Rationale: The correct answer is A: Provide positive pressure ventilation with supplemental oxygen. This is the most appropriate action as the patient is cyanotic, responsive to painful stimuli, and exhibiting stridorous respirations, indicating potential airway compromise. Providing positive pressure ventilation with supplemental oxygen can help improve oxygenation and support the patient's breathing. Summary of other choices: B: Obtaining vital signs is important, but in this urgent situation, addressing the airway and breathing takes precedence. C: Contacting medical direction may delay essential treatment. Immediate intervention is crucial in this scenario. D: Applying a pulse oximeter can provide valuable information, but administering oxygen and ensuring adequate ventilation should be the priority in a patient with compromised breathing.

Correct Answer: B

Rationale: The correct answer is B: Lymph node. A mobile mass that is palpable and moves in multiple directions is characteristic of a lymph node. Lymph nodes are small, bean-shaped structures that are part of the immune system and can move freely when touched. Incorrect choices: A: Cancer - A cancerous mass would typically be fixed and not mobile. C: Deep scar - Scars are usually fixed and do not move when touched. D: Muscle - Muscles are usually deeper in the body and not typically palpable as a mobile mass.

Correct Answer: A

Rationale: The correct answer is A: The fovea. The fovea is the central focal point for incoming images because it contains a high concentration of cones, which are responsible for detailed central vision. Cones are essential for color vision and visual acuity. The macula, while important for central vision, refers to the area surrounding the fovea. The optic disk is where the optic nerve exits the eye, and it does not receive incoming images. The physiologic cup is a normal depression in the optic nerve head and is not involved in image reception. In conclusion, the fovea is the correct answer as it is the area with the highest visual acuity due to the dense concentration of cones.

Correct Answer: B

Rationale: The correct answer is B: Small amplitude, weak. In congestive heart failure, the heart's ability to pump effectively is compromised, leading to decreased cardiac output. This results in a weakened pulse with reduced amplitude. Palpating a small, weak pulse in this patient is expected due to poor cardiac function. Choices A and C are incorrect because a large, forceful pulse is not expected in congestive heart failure, and a normal pulse may not reflect the compromised cardiac function. Choice D, bigeminal, refers to an abnormal rhythm characterized by every other heartbeat being premature and is not typically associated with congestive heart failure.

Correct Answer: B

Rationale: The correct answer is B: Every year. Annual assessment aligns with American Heart Association guidelines to monitor these key health indicators regularly for early detection and management of potential cardiovascular risks. More frequent assessments (A) may be unnecessary and burdensome. Less frequent assessments (C, D) increase the risk of missing important changes in health status that could lead to adverse outcomes. Regular yearly assessments allow for timely interventions and adjustments to promote optimal cardiovascular health.

Correct Answer: C

Rationale: The correct answer is C: Advise them to file an advanced directive. An advanced directive is a legal document that allows individuals to specify their healthcare preferences in advance, including who they want to make medical decisions for them if they are unable to do so. In this scenario, since the patient and her partner are not married, it is important for her to have an advanced directive in place to ensure that her partner is legally recognized as the decision-maker. This documentation will help ensure her goals of care are followed in case she becomes incapacitated. Choice A (Advise them to complete a POLST) is incorrect because a POLST (Physician Orders for Life-Sustaining Treatment) form is used to specify a patient's wishes for end-of-life care, not for designating a medical decision-maker. Choice B (Advise them that they have adequate documentation to be recognized legally) is incorrect because without an advanced directive, there may be legal challenges to the partner's authority to make medical decisions

Correct Answer: A

Rationale: The correct answer is A because in an older adult with an indwelling urinary catheter, a fever >100°F can be a sign of urinary tract infection (UTI) or urosepsis. Given her acute decline in mental status and fever, empiric antibiotic therapy is warranted to treat a potential infection. Choice B is incorrect because older adults with indwelling catheters are at increased risk for UTIs and bloodstream infections. Choice C is incorrect as obtaining a urine culture is important to confirm the diagnosis and guide appropriate antibiotic therapy. Choice D is incorrect as the duration of antibiotic treatment for a UTI is typically longer than 3 days.

Correct Answer: B

Rationale: The correct answer is B: Hirsutism. Hirsutism is the presence of excessive hair growth in a male pattern distribution in women, which is a common sign of hyperandrogenism. Elevated androgen levels can lead to hirsutism in women, especially in conditions like polycystic ovary syndrome. High pitch voice (A) and obesity (D) are not direct indicators of hyperandrogenism. While polycystic ovaries (C) can be associated with hyperandrogenism, the presence of hirsutism is a more specific and direct finding in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Provide positive pressure ventilation with supplemental oxygen. This is the most appropriate action as the patient is cyanotic, responsive to painful stimuli, and exhibiting stridorous respirations, indicating potential airway compromise. Providing positive pressure ventilation with supplemental oxygen can help improve oxygenation and support the patient's breathing. Summary of other choices: B: Obtaining vital signs is important, but in this urgent situation, addressing the airway and breathing takes precedence. C: Contacting medical direction may delay essential treatment. Immediate intervention is crucial in this scenario. D: Applying a pulse oximeter can provide valuable information, but administering oxygen and ensuring adequate ventilation should be the priority in a patient with compromised breathing.
