A mother runs into the emergency department with a toddler in her arms and tells the nurse that her child got into some cleaning products. The child smells of chemicals on the hands, face, and on the front of the child's clothes. After ensuring the airway is patent, which action should the nurse implement first?

Determine type of chemical exposure.

Call poison control emergency number.

Assess child for altered sensorium.

Obtain equipment for gastric lavage.

Answer and Explanation

The Correct Answer is A

A. Determining the type of chemical exposure is critical as it guides subsequent treatment and interventions. Different chemicals require different management strategies, including whether to induce vomiting or administer activated charcoal.

B. Calling poison control is important but should occur after identifying the specific chemical involved, as the poison control guidelines often depend on the substance the child was exposed to.

C. Assessing for altered sensorium is important, but the immediate priority is to identify the type of chemical exposure to implement appropriate interventions.

D. Obtaining equipment for gastric lavage may be necessary in certain cases, but this is based on the type of chemical ingested and the child's condition. Identifying the chemical exposure must occur first to determine if gastric lavage is appropriate.

Correct Answer is C

Explanation

A. BRCA1 and BRCA2 provide protection of mature, functioning breast and ovarian cells. This is not accurate; BRCA1 and BRCA2 genes are involved in DNA repair, and mutations in these genes increase cancer risk.
B. The choice of treatment is best determined by the sensitivity of these genetic markers. While genetic markers can influence treatment decisions, this option does not directly address the role of BRCA1 and BRCA2 mutations in cancer risk.
C. Mutations in BRCA1 or BRCA2 identify a client's risk for cancerous cell development in breast tissue. This is correct. Mutations in these genes significantly increase the risk of developing breast and ovarian cancer.
D. The prognosis of breast cancer is most successful when these markers are inherited mutations.
This statement is incorrect. The presence of BRCA1 or BRCA2 mutations influences risk, not necessarily prognosis or treatment success.

A. Apply a water-soluble lubricant to the catheter. B. Wear protective goggles while performing the procedure. C. Instill 3 mL of normal saline before suctioning. D. Instruct the client to cough as the suction tip is removed.

Correct Answer is B

Explanation

A. Apply a water-soluble lubricant to the catheter. Lubricating the suction catheter can facilitate insertion, but applying a lubricant is not the primary action needed to address excessive drooling.
Additionally, water-soluble lubricants may not provide adequate protection against potential splashes or droplets.
B. Wear protective goggles while performing the procedure. Excessive drooling in a client with ALS may increase the risk of exposure to saliva and potential aerosolized droplets during
suctioning. Wearing protective goggles helps prevent exposure to bodily fluids and reduces the risk of infection for the nurse.
C. Instill 3 mL of normal saline before suctioning. Instilling normal saline before suctioning is not typically indicated for oral suctioning in a client with excessive drooling. This action may increase the risk of aspiration and is unnecessary for managing drooling.
D. Instruct the client to cough as the suction tip is removed. Instructing the client to cough is not appropriate for oral suctioning. Coughing may increase the production of saliva and exacerbate drooling. Additionally, this action does not address the nurse's safety during the suctioning
procedure.
