Fundamentals of Nursing HESI

Correct Answer: A

Rationale: Proper surgical hand-washing technique involves keeping the hands higher than the elbows to prevent contamination. Washing with hands held lower than the elbows can lead to potential contamination. Using a brush to scrub under the nails is not recommended as it can cause microabrasions, increasing infection risk. While washing for at least 30 seconds is a good practice for thorough hand hygiene, hand positioning is critical during surgical hand-washing. Using alcohol-based hand rub alone is insufficient for surgical hand-washing as it may not effectively remove dirt, debris, and transient microorganisms.

Correct Answer: A

Rationale: Postural hypotension is a common sign of extracellular fluid volume deficit due to decreased blood volume, leading to a drop in blood pressure upon standing. Distended neck veins, dependent edema, and bradycardia are not typically associated with extracellular fluid volume deficit. Distended neck veins are more indicative of fluid volume overload, dependent edema is a sign of fluid retention, and bradycardia is not a common finding in extracellular fluid volume deficit.

Correct Answer: C

Rationale: The correct answer is C. Telangiectatic nevi, often referred to as 'stork bites,' are common birthmarks in infants and are considered normal. These birthmarks usually fade and disappear as the child grows older. Choices A, B, and D are incorrect because Mongolian spots are bluish-gray birthmarks commonly found in darker-skinned infants, port wine stains are vascular birthmarks that typically do not disappear, and surgical removal is not recommended for telangiectatic nevi as they usually resolve on their own.

Correct Answer: A

Rationale: The correct answer is A. Obtaining cotton balls for tracheostomy care is not recommended due to the risk of fiber contamination. Sterile gauze should be used instead. Choice B, using a sterile water bottle, is a correct and appropriate action for tracheostomy care to maintain cleanliness. Choice C, checking the suction equipment, is also a necessary step to ensure it is functioning properly for the procedure. Choice D, wearing a sterile gown, is a standard precaution to maintain a sterile environment during tracheostomy care.

Correct Answer: C

Rationale: Cough with bloody sputum is a hallmark symptom of tuberculosis and is highly concerning as it indicates active disease. Hemoptysis (coughing up blood) is associated with tuberculosis infection in the lungs. While night sweats and weight loss are common symptoms of tuberculosis, they are less specific than coughing with bloody sputum. Fatigue is a nonspecific symptom that can be present in various conditions and is not specific to tuberculosis.
