Question 1 of 5
A patient is seen in the clinic for reports of "fainting episodes that started last week."? How would the nurse proceed with the examination?
Correct Answer: C
Rationale: When a patient reports fainting episodes, it is crucial to assess for orthostatic hypotension. If the nurse suspects volume depletion, the patient has hypertension, is on antihypertensive medications, or has a history of fainting or syncope, blood pressure readings should be taken in three positions: lying, sitting, and standing. This assessment helps detect orthostatic hypotension, which can provide valuable information about the patient's condition. Taking blood pressure readings in multiple positions allows for a comprehensive evaluation of possible postural changes in blood pressure.
Choices A, B, and D are incorrect because they do not cover the necessary positions to assess for orthostatic hypotension effectively.
Question 2 of 5
When preparing a patient on complete bed rest to eat, at what degree angle or more should you put the head of the bed up?
Correct Answer: D
Rationale: The correct answer is D: 30. When a patient is on complete bed rest, it is essential to elevate the head of the bed at a 30-degree angle or more before meals. This position helps prevent choking and aspiration of food during eating by promoting proper swallowing and digestion.
Choices A, B, and C are incorrect because they do not provide the optimal elevation needed to support safe and effective feeding for a patient on complete bed rest.
Question 3 of 5
During an examination, the nurse notices that a female patient has a round "moon"? face, central trunk obesity, and a cervical hump. Her skin is fragile with bruises. The nurse determines that the patient likely has which condition?
Correct Answer: C
Rationale: Cushing syndrome is characterized by weight gain and edema with central trunk and cervical obesity (buffalo hump) and a round, plethoric face (moon face). Excessive catabolism in Cushing syndrome causes muscle wasting, weakness, thin arms and legs, reduced height, and thin, fragile skin with purple abdominal striae, bruising, and acne. Gigantism is characterized by increased height and weight and delayed sexual development, which are not present in the patient. Acromegaly results from excessive growth hormone secretion in adulthood, leading to bone overgrowth in specific areas like the face, head, hands, and feet. Marfan syndrome is an inherited connective tissue disorder characterized by a tall, thin stature and distinct features not seen in this patient. The combination of signs described in the question aligns with the clinical presentation of Cushing syndrome.
Question 4 of 5
A 70-year-old man has a blood pressure of 150/90 mm Hg in a lying position, 130/80 mm Hg in a sitting position, and 100/60 mm Hg in a standing position. How should the nurse evaluate these findings?
Correct Answer: B
Rationale: The correct answer is, 'The change in blood pressure readings is called orthostatic hypotension.' Orthostatic hypotension is defined as a drop in systolic pressure of ³20 mm Hg or ³10 mm Hg drop in diastolic pressure that occurs with a quick change to a standing position. This condition is common in individuals on prolonged bed rest, older adults, those with hypovolemia, or taking specific medications. The blood pressure readings provided in the question (150/90 mm Hg lying, 130/80 mm Hg sitting, and 100/60 mm Hg standing) demonstrate a significant change in blood pressure with position changes, which is indicative of orthostatic hypotension.
Choices A, C, and D are incorrect because the readings do not indicate a normal response or blood pressure within normal limits for the patient's age; rather, they suggest the presence of orthostatic hypotension.
Question 5 of 5
The healthcare provider is examining a patient who is reporting "feeling cold."? Which is a mechanism of heat loss in the body?
Correct Answer: B
Rationale: When the body needs to lose heat, one of the mechanisms it employs is radiation. Radiation involves the transfer of heat from the body to the environment in the form of infrared waves. While metabolism, exercise, and food digestion contribute to heat production, they are not mechanisms for heat loss. Metabolism generates heat as a byproduct, exercise increases metabolic rate leading to heat production, and food digestion involves some heat generation, but these processes do not directly facilitate heat loss.
Therefore, in the scenario where the patient is feeling cold, radiation is the primary mechanism for the body to lose excess heat and maintain a stable internal temperature.
