A patient will be starting therapy with a corticosteroid. The nurse reviews the prescriber's orders and notes that an interaction may occur if the corticosteroid is taken with which of these drug classes?

Choice A reason: Respiratory rate and heart rate are not specific indicators of oxygen saturation. They can be affected by many other factors, such as pain, anxiety, or dehydration.

Choice B reason: Blood pressure and temperature are not directly related to oxygen saturation. They can be influenced by other conditions, such as infection, inflammation, or shock.

Choice C reason: Lung sounds and chest expansion are relevant parameters to monitor for a client with low oxygen saturation. They can indicate the presence of respiratory problems, such as pneumonia, asthma, or atelectasis, that can impair gas exchange and oxygen delivery.

Choice D reason: Hemoglobin and hematocrit are measures of red blood cell count and volume. They can affect the oxygen-carrying capacity of the blood, but they are not directly affected by oxygen saturation. They can be altered by other factors, such as bleeding, dehydration, or anemia.

Choice A reason: Constipation is not an adverse effect of tamoxifen. Tamoxifen does not affect the gastrointestinal motility or function. Constipation may be caused by other factors such as dehydration, low-fiber diet, or lack of exercise.

Choice B reason: Clotting is an adverse effect of tamoxifen. Tamoxifen can increase the risk of thromboembolic events such as deep vein thrombosis, pulmonary embolism, or stroke. Clotting can cause serious complications such as pain, swelling, shortness of breath, chest pain, or neurological deficits.

Choice C reason: Tinnitus is not an adverse effect of tamoxifen. Tamoxifen does not affect the auditory system or cause hearing loss. Tinnitus may be caused by other factors such as noise exposure, ear infection, or medication toxicity.

Choice D reason: Urinary retention is not an adverse effect of tamoxifen. Tamoxifen does not affect the urinary system or cause bladder dysfunction. Urinary retention may be caused by other factors such as prostate enlargement, nerve damage, or medication side effects.
