The child is a 2-year-old who fell into a pool. He was retrieved from the pool by a family member but was not breathing. The family member started CPR, and the ambulance brought him to the hospital.
What factors are important in determining the level of hypoxemia that the child may have experienced during the submersion?
Select all that apply.
Temperature of water
The weight of the child
Oxygen concentration of the ambient air
Whether or not anyone witnessed the fall into the pool
The amount of time the child was submerged
Correct Answer : A,E
The level of hypoxemia that the child may have experienced during the submersion depends on several factors, but the most important ones are:
- The **temperature of water**: Cold water can induce a diving reflex, which lowers the heart rate and oxygen consumption, and may protect the brain from hypoxic injury. Cold water can also cause laryngospasm, which prevents water aspiration but also impairs gas exchange.
- The **amount of time the child was submerged**: The longer the submersion, the more severe the hypoxemia and the higher the risk of brain damage and death. The survival rate decreases significantly after 5 minutes of submersion.
The other factors are less relevant or not directly related to the level of hypoxemia:
- The **weight of the child**: This may affect the buoyancy and the ability to float or swim, but not the oxygen consumption or gas exchange during submersion.
- The **oxygen concentration of the ambient air**: This may affect the pre-submersion oxygen saturation, but not the rate of oxygen depletion or gas exchange during submersion.
- The **witnessing of the fall into the pool**: This may affect the time to rescue and resuscitation, but not the level of hypoxemia during submersion.

Correct Answer is B
Explanation
Choice A rationale:
Emphasize that using safe sex practices removes the risk of STIs. Rationale: While promoting safe sex practices is essential in preventing STIs, this response is not directly addressing the client's situation. The client already reports having unprotected sex, so this choice does not provide relevant information or address the potential consequences.
Choice B rationale:
Explain that reinfections occur from sex with untreated partners. Rationale: This is the correct response. Syphilis is a sexually transmitted infection that can be treated with antibiotics, but reinfections can occur if sexual partners are not treated. This response provides essential information about the potential consequences of unprotected sex with untreated partners.
Choice C rationale:
Clarify that all STIs are transmitted through sexual intercourse. Rationale: While this statement is accurate in a general sense, it does not specifically address the client's situation or the risks associated with syphilis. It lacks the focus needed to educate the client effectively about their current situation.
Choice D rationale:
Provide counseling that most contraceptives protect against infection. Rationale: This response is inaccurate. Contraceptives primarily aim to prevent pregnancy, not protect against STIs. Therefore, it does not address the client's concern or provide relevant information about syphilis.
Correct Answer is A
Explanation
Choice B rationale:
Giving the wife a straw to help facilitate the client's drinking is not the most appropriate action in this situation. The client's facial paralysis and inability to move his left side could be indicative of a possible stroke or cerebral vascular accident (CVA). Before attempting to give the client fluids, it is essential to assess his swallowing reflex to prevent aspiration and ensure safety. Using a straw may not address the underlying issue.
Choice C rationale:
Assisting the wife and carefully giving the client small sips of water without assessing the swallowing reflex can be risky. If the client has impaired swallowing, this action could lead to aspiration and further complications. Assessing the client's ability to swallow is the priority to ensure safe oral intake.
Choice D rationale:
Obtaining thickening powder before providing any more fluids is premature without first assessing the client's swallowing ability. Thickened liquids may be necessary if the client has dysphagia, but the nurse should assess the client's condition and consult with the healthcare provider before making this decision. Assessing the swallowing reflex is the first step in determining the appropriate course of action.
