Preschoolers' fears can best be dealt with by which intervention?

A. Serum calcium:

- Serum calcium levels are not typically used to diagnose cystic fibrosis. Calcium levels are more related to bone health, neuromuscular function, and various metabolic processes. While electrolyte imbalances can occur in CF, serum calcium alone is not specific for its diagnosis.

B. Urine creatinine:

- Urine creatinine is not a diagnostic test for cystic fibrosis. Creatinine is a waste product produced by muscles and excreted by the kidneys. Monitoring creatinine levels is more related to assessing kidney function and is not specific to CF diagnosis.

C. Sweat chloride test:

- The sweat chloride test is considered the gold standard for diagnosing cystic fibrosis. Individuals with CF have higher than normal levels of chloride in their sweat. This test measures the amount of chloride in the sweat, and a high level is indicative of CF. It is a noninvasive and reliable diagnostic test for CF.

D. Bronchoscopy:

- Bronchoscopy is not used as a primary diagnostic test for cystic fibrosis. While it may be performed for other reasons, such as assessing airway abnormalities or obtaining samples for culture, it is not the primary method for diagnosing CF.

A. "This is common for teens to threaten suicide when they want attention."

This statement is dismissive and could contribute to a lack of appropriate intervention. It is essential not to trivialize or assume that all suicide threats are attention-seeking, as they may indicate underlying distress and a need for support.

B. "Your friend's threat needs to be taken seriously and immediate help for your friend is important."

This is the most appropriate response. It acknowledges the seriousness of the situation, emphasizes the need for immediate help, and reflects a responsible and caring approach to addressing a friend's mention of suicide.

C. "If your friend mentions suicide a second time, you will want to get your friend some help."

Waiting for a second mention is not appropriate, as any mention of suicide should be treated seriously. Delaying intervention until a second mention could be dangerous, as the friend may be in immediate distress.

D. "You need to gather details about your friend's suicide plan."

While gathering information about a friend's thoughts and plans is important for a comprehensive assessment, it is not the primary concern in the immediate response to a suicide mention. The immediate focus should be on ensuring the friend's safety and involving appropriate professionals for help.
