The reservoir bag on a nonrebreather mask should not collapse with exhalation. It is designed to maintain a continuous flow of oxygen and reserve a volume of oxygen for the patient to inhale with each breath.
 

While high-flow oxygen can dry a patient's mucous membranes, a nonrebreather mask typically has a high oxygen flow rate, and humidification can be used to prevent drying.
 

A nonrebreather mask is used to deliver high-flow oxygen, not low-flow. It is designed to provide a high concentration of oxygen, typically around 60% to 90% FiO2.


 

Granola may contain ingredients like nuts and dried fruits that are high in potassium, which is not
suitable for a low potassium diet.
 

Molasses is high in potassium, so replacing sugar with molasses when baking would not be
appropriate for someone on a low potassium diet.
 

Orange juice is high in potassium compared to apple juice, making it an unsuitable choice for
someone on a low potassium diet.
 

A healthy stoma should be pink or red in color. A purple or dark-colored stoma may indicate poor blood flow and could be a sign of complications requiring immediate medical attention.

A sigmoid colostomy usually results in the production of more formed stool because it is located closer to the rectum, where most of the water has been absorbed. Expecting unformed stool is more typical of a colostomy in the ascending or transverse colon.

While some discomfort is normal postoperatively, the stoma itself should not be persistently painful. Pain management and proper care should be addressed, but ongoing severe pain could indicate complications.

Flexible sigmoidoscopy is used to examine the lower part of the colon, which is not typically

associated with symptoms of heartburn.

A colonoscopy is used to view the entire colon and is not the first choice for investigating heartburn,

as this symptom is not directly related to the colon.

Warm water should be used to clean the skin, as hot water can cause further irritation.
 

Friction should be avoided when drying the skin to prevent damage. The skin should be patted dry
gently.
 

Soap can be too harsh and drying for the skin, especially if it is already compromised by incontinence. A mild, pH-balanced cleanser is recommended.
 

The small intestine is not the starting point of the digestive process. It is where most of the digestion and absorption of nutrients occurs after the food has been processed in the stomach.
 

The rectum is the final section of the large intestine, where feces are stored before being expelled. It is not involved in the initial stages of digestion.
 

The stomach is involved in the early stages of digestion, particularly in the breakdown of proteins, but it is not the starting point. Food enters the stomach after being ingested through the mouth.
 

Dark-colored urine can be a sign of dehydration or the presence of certain substances in the urine, such as blood or bile, but it is not typically associated with urinary retention.
 

Blood in the urine, or hematuria, can indicate various conditions, including infections, stones, or tumors, but it is not a common finding specifically associated with urinary retention.
 

Cloudy urine may suggest the presence of phosphates (a normal occurrence in alkaline urine), infection, or the presence of pus (pyuria). While it could be associated with a urinary tract infection that might lead to urinary retention, cloudy urine itself is not a direct indicator of urinary retention.
 

Weight loss is not typically associated with circulatory overload. In fact, weight gain may occur due
to fluid retention.
 

Diaphoresis, or excessive sweating, can be associated with circulatory overload as the body attempts to cool down due to the increased blood volume and workload on the heart.
 

Hypotension, or low blood pressure, is not a usual finding in circulatory overload. Instead, hypertension may be more likely due to the increased volume of fluid in the blood vessels.

A pleural friction rub is associated with conditions that cause pleural inflammation, such as pleuritis or pneumonia, rather than Chronic Obstructive Pulmonary Disease (COPD). While patients with COPD may experience other abnormal lung sounds like wheezing or crackles, pleural friction rubs are not typically a feature of COPD.

Spoon nails (koilonychia) are typically associated with iron deficiency anemia or other conditions affecting the circulatory system. Although COPD is a chronic respiratory condition that can impact oxygenation, spoon nails are not commonly associated with COPD. This condition is more commonly seen in anemia or other nutritional deficiencies.

Hyperresonance on percussion is a typical finding in COPD, especially in those with emphysema, where air trapping occurs. This is due to the destruction of lung tissue and the over-inflation of alveoli, which creates a more resonant sound when the chest is percussed. This finding indicates the presence of hyperinflated lungs, a hallmark of emphysema and a common component of COPD.

Wearing sterile gloves is not necessary when draining an ileostomy bag as this is not a sterile procedure. Clean gloves are typically used.
 

Washing the skin surrounding the ileostomy with hot water is not recommended as it can cause
irritation. Lukewarm water should be used, and the area should be patted dry.

The ileostomy bag should be emptied when it is one-third to one-half full to prevent leakage and ensure comfort for the client.
