A nurse is providing teaching to a client who has gastroesophageal reflux disease. Which of the following statements should the nurse include in the teaching?

A) Cleanse the client's finger with an antiseptic swab: The first step in performing a capillary blood glucose test is to cleanse the client’s finger with an antiseptic swab. This reduces the risk of infection and ensures that any contaminants on the skin do not affect the accuracy of the blood glucose reading.

B) Hold the client's finger in a dependent position: Holding the finger in a dependent position can help increase blood flow, but this step is taken after cleansing the finger. The priority is to first clean the area to minimize the risk of infection.

C) Wipe away the first drop of blood: Wiping away the first drop of blood is done to avoid contamination from interstitial fluid and to ensure a more accurate reading. However, this action occurs after the blood sample is obtained, not before the test begins.

D) Place the lancet on the side of the selected finger: While placing the lancet on the side of the finger is important for minimizing discomfort and obtaining an adequate blood sample, it follows the initial steps of cleaning the finger and preparing for the blood draw.

A) Cimetidine: Cimetidine is an H2 receptor antagonist used to reduce stomach acid and treat conditions such as peptic ulcers and gastroesophageal reflux disease (GERD). It is not used to manage metabolic acidosis.

B) Calcitonin: Calcitonin is used to regulate calcium levels and treat conditions like osteoporosis or hypercalcemia. It does not address metabolic acidosis and is not appropriate for this condition.

C) Sodium bicarbonate: Sodium bicarbonate is commonly used to treat metabolic acidosis. It works by neutralizing excess acid in the blood, thereby increasing the blood's pH and helping to correct the acid-base imbalance associated with metabolic acidosis.

D) Sodium chloride: Sodium chloride is a salt that can be used to manage fluid and electrolyte imbalances but does not correct metabolic acidosis. It is not suitable for treating the acid-base imbalance seen in metabolic acidosis.
