A public health nurse is assessing an older adult client who lives with a family member.

The nurse identifies several bruises in various stages of healing. The client and family members explain that the bruises are a result of clumsiness. However, based on the distribution of the bruises, the nurse suspects abuse.

Which of the following actions should the nurse take first?

Investigate further to confirm the suspicion.

Report the findings.

Provide the client with a crisis hotline number.

Discuss respite care with the client’s family.

Answer and Explanation

The Correct Answer is B

The nurse has a legal and ethical obligation to report any suspected abuse of a vulnerable client, such as an older adult. Reporting the findings is the first action the nurse should take to protect the client and initiate an investigation by the appropriate authorities.

Choice A is wrong because investigating further to confirm the suspicion is not within the nurse’s scope of practice and could delay the reporting process.

Choice C is wrong because providing the client with a crisis hotline number is not enough to ensure the client’s safety and well-being.

The client might not be able to access the hotline or might be afraid to use it.

Choice D is wrong because discussing respite care with the client’s family is not appropriate at this stage.

The nurse should not assume that the family member is willing or able to provide adequate care for the client.

Respite care might be an option after the abuse is reported and investigated.

Correct Answer is D

Explanation

This is because heat loss by conduction occurs when two objects with different temperatures come into direct contact with each other. The baby’s skin would lose heat to the cold scale by conduction if there was no warm blanket between them.

Choice A is wrong because closing doors and windows to prevent draft (current of air with motion) would prevent heat loss by convection, not conduction. Convection is the transfer of heat from a body to moving molecules such as air or liquid.

Choice B is wrong because keeping a hat on the baby’s head would prevent heat loss by radiation, not conduction. Radiation is the transfer of heat from a body to the surroundings by electromagnetic waves.

Choice C is wrong because thoroughly drying infant after a bath would prevent heat loss by evaporation, not conduction. Evaporation is the process of liquid changing into gas and carrying away heat from the body surface.

A. Instruct the client to use pursed-lip breathing. B. Plan to have the client lay down for 1 hr after meals. C. Restrict the client’s fluid intake to less than 1 L/day. D. Encourage the client to use the upper chest for respiration.

Correct Answer is A

Explanation

Pursed-lip breathing is a technique that helps to slow down the breathing rate and keep the airways open longer. This improves gas exchange and reduces the work of breathing. Pursed-lip breathing also helps to prevent air trapping and hyperinflation of the lungs, which are common complications of COPD.

Choice B is wrong because laying down for 1 hour after meals can increase the pressure on the diaphragm and make breathing more difficult. It can also increase the risk of aspiration and reflux.

Choice C is wrong because restricting the client’s fluid intake to less than 1 L/day can lead to dehydration and thickening of secretions, which can obstruct the airways and impair gas exchange. Fluid intake should be adequate to maintain hydration and thin secretions.

Choice D is wrong because using the upper chest for respiration is a sign of inefficient breathing and respiratory distress.

It can increase the oxygen demand and cause fatigue. The client should be encouraged to use the diaphragm and abdominal muscles for respiration, which are more efficient and reduce the work of breathing.

Normal ranges for oxygen saturation are 95% to 100%, for arterial blood gas pH are 7.35 to 7.45, for PaCO2 are 35 to 45 mmHg, for PaO2 are 80 to 100 mmHg, and for HCO3 are 22 to 26 mEq/L.
