The nurse is teaching the client about incentive spirometry in the preoperative unit. Which statement regarding incentive spirometry should the nurse include with preoperative teaching?

"Failure to keep your lungs working may result in pneumonia after surgery which could, in turn, result in death."

"Incentive spirometry is conducted routinely after surgery and will be demonstrated when you return from surgery."

"You will use the incentive spirometer for the first postoperative day until deep breathing and coughing can be done comfortably."

"Deep breathing exercises are encouraged to maintain lung capacity and to strengthen respiratory muscles, which will help prevent complications."

Answer and Explanation

The Correct Answer is D

Choice A reason: While it is important to communicate the risks of not using the incentive spirometer, this statement is overly alarming and may cause unnecessary anxiety for the client. It is better to focus on positive outcomes and preventive measures.

Choice B reason: This statement informs the client that incentive spirometry is routine and will be demonstrated postoperatively, but it does not provide specific details about its benefits or importance.

Choice C reason: This statement explains the use of the incentive spirometer on the first postoperative day, but it does not address the overall goal of preventing complications through lung exercises.

Choice D reason: This statement effectively explains the purpose and benefits of deep breathing exercises, including using the incentive spirometer. It emphasizes the importance of maintaining lung capacity and strengthening respiratory muscles to prevent complications, providing a clear rationale for the intervention.

Correct Answer is C

Explanation

Choice A reason: The degree of skin elasticity is a measure often used to assess hydration status, especially in older adults. However, it does not provide direct information about the client's cardiac function or the cause of their current symptoms.

Choice B reason: The length of capillary refill is useful for assessing peripheral perfusion and overall circulatory status. While prolonged capillary refill can indicate poor perfusion, it does not provide specific information about heart rhythm or the cause of palpitations and faintness in a client with heart failure.

Choice C reason: The rhythm of the apical pulse is the most important assessment data to obtain in this scenario. The client's complaint of a fast-beating heart and feeling faint suggests a possible arrhythmia, which could be detected by assessing the rhythm of the apical pulse. This assessment can help identify irregular heartbeats, tachycardia, or other abnormalities that may require immediate intervention.

Choice D reason: The volume of pedal pulses can provide information about peripheral circulation, but it is not as crucial as assessing the heart rhythm in a client experiencing palpitations and faintness. Peripheral pulse volume may not change significantly with certain arrhythmias or cardiac issues that affect the central circulation more directly.

A. Serum potassium 5.0 me/L (5.0 mmol/L), serum sodium 138 me/L (138 mmol/L). B. Serum potassium 4.5 me/L (4.5 mmol/L), serum sodium 140 me/L (140 mmol/L). C. Serum potassium 3.5 me/L (3.5 mmol/L), serum sodium 142 me/L (142 mmol/L). D. Serum potassium 3.0 me/L (3.0 mmol/L), serum sodium 149 me/L (149 mmol/L).

Correct Answer is D

Explanation

Choice A reason: Serum potassium of 5.0 me/L and serum sodium of 138 me/L are within normal ranges and do not reflect the expected electrolyte imbalances due to dehydration from vomiting and diarrhea.

Choice B reason: Serum potassium of 4.5 me/L and serum sodium of 140 me/L are also within normal ranges. This does not reflect the typical imbalance caused by dehydration.

Choice C reason: Serum potassium of 3.5 me/L and serum sodium of 142 me/L are normal values. They do not indicate the electrolyte disturbances expected with dehydration from vomiting and diarrhea.

Choice D reason: Serum potassium of 3.0 me/L indicates hypokalaemia (low potassium), and serum sodium of 149 me/L indicates hypernatremia (high sodium). These imbalances are expected in a client with a history of fever, vomiting, and diarrhea, as these conditions can lead to loss of potassium and concentration of sodium due to dehydration.
