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 B

Explanation

Choice A rationale:

Hemoptysis, which is the coughing up of blood, is not typically associated with a urinary tract infection (UTI). It is more commonly related to respiratory or pulmonary issues.

Choice B rationale:

Hematuria, the presence of blood in the urine, is a common finding in a UTI. Inflammation and infection in the urinary tract can lead to the presence of blood cells in the urine.

Choice C rationale:

Hyperglycemia, an elevated blood glucose level, is not directly related to a UTI. It may be seen in individuals with diabetes, but it is not a typical finding in a UTI.

Choice D rationale:

Hypocalcemia, a low level of calcium in the blood, is not a characteristic finding in a UTI. UTIs primarily affect the urinary system and do not directly involve calcium metabolism.

A. A pearly, waxy nodule. B. An irregular border on a variegated-colored lesion. C. A firm, nodular, crusty, or ulcerated lesion. D. A weeping vesicle.

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
