When auscultating over the apex of the client's lung field, what breath sound should the nurse expect to hear?

Bronchovesicular

Vesicular

Bronchial

Crackles

Answer and Explanation

The Correct Answer is B

B. Heard over most of the lung fields, except for the major bronchi and the trachea.

Low intensity and pitch, with a longer inspiratory phase than expiratory phase. They are softer and more breezy in quality. Vesicular breath sounds are heard over the peripheral lung fields, including the apex (top) of the lungs.

A. Heard over the major bronchi, which are near the sternum and between the scapulae. They are of intermediate intensity and pitch, with equal inspiration and expiration phases. They are typically heard in the 1st and 2nd intercostal spaces along the sternal border and between the scapulae.

C. Heard over the trachea and larynx.

Characteristics: High intensity and pitch, with a short inspiratory phase and a longer expiratory phase. They are louder and harsher in quality, resembling the sound of air blowing through a hollow pipe.

D. Crackles are abnormal breath sounds that can be fine or coarse.

Fine crackles are high-pitched, short, popping sounds heard during inspiration, often due to fluid in the small airways or alveoli.

Coarse crackles are loud, low-pitched, bubbling sounds heard during inspiration, typically due to the presence of secretions in the larger airways.

Correct Answer is B

Explanation

B. Teaching preschoolers how to wash their hands correctly is an example of primary prevention. By educating children on proper hand hygiene practices, nurses aim to reduce the spread of infections and promote good health habits. This activity focuses on preventing the transmission of infectious diseases and promoting overall wellness among children

A. Screening for high blood pressure is an example of secondary prevention rather than primary prevention. Secondary prevention involves early detection and treatment to halt or slow down the progress of a disease.

C. Providing hospice care is a form of palliative care that focuses on improving the quality of life for terminally ill clients and their families. It aims to provide comfort and support rather than preventing disease onset. Therefore, it does not fall under primary prevention but rather under supportive care for those with advanced illness.

D. Teaching a client how to self-administer insulin is an example of tertiary prevention. Tertiary prevention involves managing and reducing the impact of a disease that has already occurred. In this case, teaching self-administration of insulin helps manage diabetes, prevent complications, and promote optimal health outcomes for the client.

A. Drugs given subcutaneously are absorbed more quickly than those given intramuscularly. B. Most drugs must enter the systemic circulation to have a therapeutic effect. C. Most oral medications are absorbed more quickly when administered with meals. D. Mucous membranes are relatively impermeable to chemicals, making absorption slow.

Correct Answer is B

Explanation

B. Drug absorption refers to the process by which a drug moves from its site of administration into the bloodstream. Once absorbed into the bloodstream (systemic circulation), drugs can distribute to various tissues and exert their therapeutic effects.

A. Different routes of drug administration affect the rate and extent of absorption. Subcutaneous injections are generally absorbed more quickly than intramuscular injections due to differences in blood flow and tissue characteristics.

C. The effect of meals on drug absorption varies depending on the specific medication. Some drugs are absorbed faster on an empty stomach, while others may be absorbed better with food.

D. Mucous membranes, contrary to the statement, are relatively permeable to drugs, allowing for rapid absorption when medications are administered via buccal, sublingual, rectal, or vaginal routes.
