The nurse is applying standard precautions in the care of a patient who has a history of human immunodeficiency virus. What key element of standard precaution?

Using appropriate personal protective equipment (PPE).

Placing patient in positive pressure isolation room

Placing patient in contact precautions

Wearing gloves at all times.

Answer and Explanation

The Correct Answer is A

A. Using appropriate personal protective equipment (PPE): Standard precautions include the use of PPE such as gloves, masks, gowns, and eye protection when caring for all patients, regardless of their known or suspected infectious status. This helps prevent the transmission of pathogens between the patient and the healthcare provider.

B. Placing patient in positive pressure isolation room: Placing a patient in a positive pressure isolation room is not a component of standard precautions. Positive pressure rooms are typically used for patients with compromised immune systems to protect them from exposure to airborne pathogens. Standard precautions should be followed regardless of the patient's room type.

C. Placing patient in contact precautions: Contact precautions involve specific measures to prevent the transmission of pathogens through direct or indirect contact with the patient or their environment. While contact precautions may be necessary for certain infectious diseases, they are not a component of standard precautions.

D. Wearing gloves at all times: While wearing gloves is part of standard precautions, it is not the only key element. Standard precautions also include other forms of PPE such as masks, gowns, and eye protection, as well as other infection control practices such as hand hygiene and environmental cleaning.

Correct Answer is D

Explanation

A. Urinary retention: While urinary retention can occur in conditions such as benign prostatic hyperplasia or neurogenic bladder, it is not a typical manifestation of hypertensive emergency. Hypertensive emergencies primarily involve acute and severe elevations in blood pressure, which can lead to target organ damage, but urinary retention is not a direct consequence.

B. Headache: Headache is a common symptom associated with hypertension, especially during hypertensive emergencies. However, it is not specific to hypertensive emergencies and can occur in less severe cases of hypertension as well.

C. Jaundice: Jaundice is not a typical manifestation of hypertensive emergency. It is more commonly associated with liver dysfunction or hemolytic disorders rather than acute elevations in blood pressure.

D. Tachycardia: Tachycardia, or an elevated heart rate, is a hallmark sign of hypertensive emergency. When blood pressure rises significantly, the heart may respond by increasing its rate to maintain cardiac output. Tachycardia is indicative of the body's compensatory mechanisms in response to the acute hypertension and can be a sign of impending cardiovascular complications.

A. Changes in peristalsis B. Decreased urine output C. Decreased insulin resistance D. Hypercholesteremia

Correct Answer is B

Explanation

A. Changes in peristalsis: Changes in peristalsis, which refers to the rhythmic contraction and relaxation of the gastrointestinal tract muscles, are not typically associated with target organ damage in hypertension. While hypertension can indirectly affect gastrointestinal function through its impact on other organ systems, such as the kidneys and cardiovascular system, alterations in peristalsis are more commonly attributed to gastrointestinal disorders or neurological conditions rather than hypertension-induced target organ damage.

B. Decreased urine output: In a patient diagnosed with hypertension, decreased urine output may indicate the development of target organ damage, particularly renal damage. Hypertension can lead to chronic kidney disease (CKD) over time, which is characterized by a gradual decline in kidney function. Decreased urine output may be a sign of impaired renal function, reduced glomerular filtration rate (GFR), or the presence of proteinuria. These changes indicate that the kidneys are no longer effectively filtering waste products and regulating fluid balance, suggesting the onset of renal damage as a consequence of long-standing hypertension.

C. Decreased insulin resistance: Hypertension is not directly linked to changes in insulin resistance. However, hypertension and insulin resistance are often comorbid conditions that share common risk factors, such as obesity, sedentary lifestyle, and unhealthy diet. While poorly controlled hypertension and insulin resistance can contribute to the development of cardiovascular disease and other complications, a decrease in insulin resistance would not typically be considered an indicator of target organ damage in hypertension.

D. Hypercholesterolemia: Hypercholesterolemia, or high levels of cholesterol in the blood, is a risk factor for cardiovascular disease, including atherosclerosis and coronary artery disease. While hypertension and hypercholesterolemia frequently coexist and contribute to the progression of vascular damage, the presence of hypercholesterolemia alone does not necessarily indicate target organ damage specific to hypertension. However, elevated cholesterol levels can exacerbate vascular changes and increase the risk of cardiovascular events in individuals with hypertension.
