A nurse is reviewing the ABGs of a client who has pneumonia. The nurse should identify which of the following findings is an indication of respiratory acidosis.

PaO2 86 mm Hg.

pH 7.4.

HCO3 16 mEq/L.

PaCO2 58 mm Hg.

Answer and Explanation

The Correct Answer is D

Choice A rationale:
A PaO2 value of 86 mm Hg is within the normal range (80-100 mm Hg) and does not indicate respiratory acidosis. PaO2 measures the partial pressure of oxygen in arterial blood.
Choice B rationale:
A pH of 7.4 is within the normal range (7.35-7.45) and does not indicate respiratory acidosis. The pH reflects the acidity or alkalinity of the blood.
Choice C rationale:
An HCO3 (bicarbonate) level of 16 mEq/L is within the normal range (22-28 mEq/L) and does not indicate respiratory acidosis. HCO3 is a measure of the metabolic component of the body's acid-base balance.
Choice D rationale:
This is the correct choice. A PaCO2 value of 58 mm Hg is elevated and indicates respiratory acidosis. PaCO2 measures the partial pressure of carbon dioxide in arterial blood, and an elevated value suggests the presence of excess carbon dioxide, leading to acidosis.

Correct Answer is A

Explanation

the correct answer is Choice A.

Choice A rationale: Basal cell carcinoma (BCC) is a type of skin cancer that develops in basal cells, a type of cell within the skin that produces new skin cells 1.One of the common symptoms of BCC is a pearly white, skin-colored or pink bump 1.This can also appear as a shiny or pearly nodule with a smooth surface 2.Therefore, a pearly, waxy nodule is a characteristic lesion of basal cell carcinoma

Choice B rationale: An irregular border on a variegated-colored lesion is more commonly associated with melanoma, another type of skin cancer, rather than basal cell carcinoma 1.While BCC can have a variety of appearances, an irregular border on a variegated-colored lesion is not typically characteristic of BCC

Choice C rationale: A firm, nodular, crusty, or ulcerated lesion can be a sign of several types of skin conditions, including squamous cell carcinoma, another type of skin cancer 1.While BCC can sometimes appear as a firm nodule 1 , the description of a crusty or ulcerated lesion is not as characteristic of BCC as a pearly, waxy nodule

Choice D rationale: A weeping vesicle is not typically associated with basal cell carcinoma 1.BCC lesions are more likely to appear as a shiny bump or nodule, or a flat, scaly patch 1.A weeping vesicle could be indicative of a different skin condition

A. A 23-year-old client who is in skeletal traction. B. A 67-year-old client who has coronary artery disease. C. A 32-year-old client who has a spinal cord injury. D. A 55-year-old client who has emphysema.

Correct Answer is C

Explanation

Choice A rationale:

A 23-year-old client in skeletal traction may be at risk of pressure injuries, but being young and presumably healthier than the other options, this client may have a lower risk compared to the other choices.

Choice B rationale:

A 67-year-old client with coronary artery disease may be at risk of pressure injuries, especially if the client has limited mobility or is bedridden. However, coronary artery disease alone does not significantly increase the risk of pressure injuries.

Choice C rationale:

A 32-year-old client with a spinal cord injury is most at risk of developing a pressure injury. Spinal cord injuries often result in paralysis or limited mobility, leading to prolonged pressure on specific areas of the body, which can cause pressure ulcers.

Choice D rationale:

A 55-year-old client with emphysema may have compromised lung function, but this alone does not significantly increase the risk of pressure injuries. Pressure injuries are primarily related to immobility and pressure on specific body areas.
