A client who has chronic renal failure and has been on dialysis for 2 years has been wondering why he is anemic. The nurse explains that anemia accompanies chronic renal failure because of:
Inadequate retention of serum sodium (Na).
Inadequate production of erythropoietin.
Blood loss in the urine.
Renal desensitization to Vitamin D.
The Correct Answer is B
Choice A reason: Inadequate retention of serum sodium is not typically associated with anemia in chronic renal failure.
Choice B reason: Inadequate production of erythropoietin is the correct answer because the kidneys produce erythropoietin, which stimulates the bone marrow to produce red blood cells. In chronic renal failure, the kidneys cannot produce enough erythropoietin, leading to anemia.
Choice C reason: While blood loss in the urine can occur, it is not the primary cause of anemia in chronic renal failure.
Choice D reason: Renal desensitization to Vitamin D affects bone health and calcium levels but is not the primary cause of anemia in chronic renal failure.

Choice A reason: Placing suction equipment at the bedside is a preparatory measure but not a preventive intervention for pulmonary complications.
Choice B reason: Performing ROM exercises is beneficial for overall mobility but does not directly prevent pulmonary complications.
Choice C reason: Administering an expectorant may help clear secretions but is not the primary preventive measure for pulmonary complications.
Choice D reason: Encouraging the use of incentive spirometry is a proven intervention to prevent pulmonary complications by promoting lung expansion and preventing atelectasis, especially in patients with a history of smoking.
Correct Answer is D
Explanation
Choice A reason: Aspirin can irritate the stomach lining and increase acid reflux, worsening GERD symptoms. It is generally not recommended without consulting a healthcare provider.
Choice B reason : Mercury content in seafood is not directly linked to GERD. This statement is misleading and does not address known risk factors for GERD.
Choice C reason : Lying down after eating can indeed increase the onset of GERD as it allows stomach contents to flow back into the esophagus more easily.
Choice D reason : Alcohol and caffeine can relax the lower esophageal sphincter, allowing stomach acid to rise into the esophagus and worsen GERD symptoms. Therefore, it is advisable to avoid or reduce their intake.
