Correct Answer: B

Rationale: The correct answer is B: Block beta stimulation in the heart. Propranolol is a beta-blocker that works by blocking the beta receptors in the heart, which reduces the heart's workload and oxygen demand, making it an effective treatment for angina. By blocking beta stimulation, propranolol helps to decrease heart rate, blood pressure, and myocardial contractility. This ultimately improves oxygen supply to the heart muscle. Explanation for other choices: A: Act as a vasoconstrictor - Propranolol does not act as a vasoconstrictor; it actually can cause vasodilation in some cases. C: Act as a vasodilator - Propranolol is not primarily a vasodilator; its main action is to block beta stimulation in the heart. D: Increase the heart rate - Propranolol actually decreases heart rate by blocking beta receptors in the heart.

Correct Answer: A

Rationale: The correct answer is A: Wilma places 2 fingers between the tie and neck. This method ensures that the tracheostomy ties are not too tightly placed by providing a standardized and easily replicable measurement. Placing 2 fingers ensures there is adequate space for proper airflow and movement without causing pressure or constriction. This method is a widely accepted practice in healthcare settings to prevent complications such as skin breakdown or restricted blood flow. Incorrect choices: B: The tracheotomy can be pulled slightly away from the neck - This does not provide a standardized measurement and may not accurately assess the tightness of the ties. C: James’ neck veins are not engorged - Monitoring neck veins does not directly correlate with the tightness of tracheostomy ties. D: Wilma measures the tie from the nose to the tip of the earlobe and to the xiphoid process - This method may not accurately reflect the appropriate tightness of the ties around the neck.

Correct Answer: A

Rationale: The correct answer is A: Risk for impaired skin integrity. This is the highest priority as patients with spinal cord injuries are at high risk for pressure ulcers due to immobility. Preventing skin breakdown is crucial to avoid complications. Choices B, C, and D are not as urgent. Choice B may be a concern but preventing skin breakdown takes precedence. Choices C and D are important but not life-threatening like potential skin issues in this patient population.

Correct Answer: B

Rationale: The correct answer is B because the assessment findings of pericarditis, photosensitivity, polyarthralgia, and painful mucous membrane ulcers are classic manifestations of systemic lupus erythematosus (SLE). Pericarditis can present as chest pain aggravated by deep breathing or lying flat, photosensitivity refers to skin rashes triggered by sunlight exposure, polyarthralgia involves joint pain in multiple joints, and painful mucous membrane ulcers are common in the mouth or nose. These findings align with the diagnostic criteria for SLE. Choices A, C, and D are incorrect because they do not align with the typical presentation of SLE. Choice A includes facial erythema which is a common symptom, but the presence of profuse proteinuria, pleuritis, fever, and weight loss are not specific to SLE. Choices C and D include symptoms like weight gain, hypothermia, and edema which are not characteristic of SLE. In summary

Correct Answer: C

Rationale: The correct answer is C because using an electric razor instead of a safety razor demonstrates understanding of the risk of injury associated with thrombocytopenia. This action shows practical application of the teaching to prevent bleeding. Choice A only indicates awareness but not necessarily action. Choice B shows knowledge but not necessarily application. Choice D is related to general healthcare knowledge but not directly linked to bleeding prevention in thrombocytopenia.
