A patient whose employment requires frequent lifting has a history of chronic back pain. After the nurse has taught the patient about correct body mechanics, which patient statement indicates the teaching has been eﬀective?

"I will tell my boss that I need a job where I can sit at my desk all day."

"I will begin doing exercises that will strengthen my lower back."

"I will keep my back straight when I am lifting heavy objects above my waist."

"I can sleep with my knees and back extended to prevent back pain."

Answer and Explanation

The Correct Answer is B

Choice A reason: Requesting a job that requires sitting all day does not reﬂect an understanding of correct body mechanics or how to manage chronic back pain through activity.

Choice B reason: Beginning exercises to strengthen the lower back indicates that the patient understands the importance of muscle strength in supporting the spine and preventing back pain.

Choice C reason: Keeping the back straight while lifting is important, but the statement about lifting "heavy objects above my waist" suggests a misunderstanding, as lifting objects above the waist increases the risk of back injury.

Choice D reason: Sleeping with knees and back extended is not recommended for preventing back pain. It is better to sleep with knees slightly bent to maintain the natural curve of the spine.

Correct Answer is A

Explanation

Choice A reason : A renal biopsy is an invasive procedure that can directly assess the extent of glomerular damage and is considered the gold standard for diagnosing the cause of abnormal GFR.

Choice B reason : Routine urinalysis can detect abnormalities in the urine but cannot quantify GFR or directly assess glomerular damage.

Choice C reason : A renal scan can evaluate renal perfusion and function but is less specific for glomerular damage compared to a biopsy.

Choice D reason : Creatinine clearance can estimate GFR but does not provide information on the specific cause of glomerular damage.

A. "It is okay to take aspirin with GERD." B. "You should avoid possible mercury-containing foods such as some seafood because of their risk to GERD." C. "There is no causal link between lying down after eating and increased onset of GERD." D. "You should avoid or cut down on alcohol and caﬀeine which can aggravate GERD."

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.
