The home care nurse is visiting a client who is totally oxygen dependent and using home oxygen. Upon noticing a gas stove in the kitchen, what teaching will the nurse provide? "It is important to eat at least five servings of vegetables daily." "Remove your oxygen before cooking near the gas stove." "An electric stove may be a safer choice for you." "Be careful not to trip over your oxygen tubing while cooking."

"An electric stove may be a safer choice for you."

The nurse educator is presenting a lecture on the respiratory and cardiovascular systems. Which response given by the nursing staff would indicate to the educator that they have an understanding of cardiac output? "If the client's stroke volume is 70 mL and heart rate is 70 beats per minute, then the cardiac output is 4.7 L/minute." "If the client's stroke volume is 80 mL and heart rate is 80 beats per minute, then the cardiac output is 6.0 L/minute." "If the client's stroke volume is 60 mL and heart rate is 60 beats per minute, then the cardiac output is 3.2 L/minute." "If the client's stroke volume is 50 mL and heart rate is 50 beats per minute, then the cardiac output is 2.5 L/minute."

"If the client's stroke volume is 50 mL and heart rate is 50 beats per minute, then the cardiac output is 2.5 L/minute." The following formula is used to determine cardiac output: Cardiac Output = Stroke Volume x Heart Rate. A client with a stroke volume of 50 mL and heart rate of 50 beats per minute has a cardiac output of 2.5 L/minute. If stroke volume is 70 and heart rate is 70 beats per minute, then the cardiac output is 4.9 L/minute. If stroke volume is 80 and heart rate is 80 beats per minute, then the cardiac output is 6.4 L/minute.

A nosebleed is noted with continued suctioning.

Prodromal stage

A person is most infectious during the prodromal stage. Early signs and symptoms of disease are present, but these are often vague and nonspecific, ranging from fatigue and malaise to a low-grade fever.

spirometer

An incentive spirometer assists the patient to breathe slowly and deeply and to sustain maximal inspiration.

Infection

An infection is a disease state that results from the presence of pathogens (disease-producing microorganisms) in or on the body.

Close contact Direct contact Indirect contact-objects NOT BY AIR

Which assessments and interventions should the nurse consider when performing tracheal suctioning? Select all that apply. Closely assess the patient before, during, and after the procedure. Hyperoxygenate the patient before and after suctioning. Limit the application of suction to 20 to 30 seconds. Monitor the patient's pulse frequently to detect potential effects of hypoxia and stimulation of the vagus nerve. Use an appropriate suction pressure (80 to 150 mm Hg). Insert the suction catheter no further than 1 cm past the length of the tracheal or endotracheal tube.

Parasites are organisms that live on or in a host and rely on it for nourishment. Malaria is a serious disease that occurs when a parasite infects a certain type of mosquito that then feeds on humans.

pursed lip breathing

Patients who experience dyspnea and feelings of panic can often reduce these symptoms by using pursed-lip breathing. Exhaling through pursed lips creates a smaller opening for air movement, effectively slowing and prolonging expiration.

How are ticks treated?

Remove tick in 24 hours by grasping with tweezers, pull out slowly, clean with antiseptic.

what is scabies

Scabies-A contagious, intensely itchy skin condition caused by a tiny, burrowing mite.

Convalescent Period

The convalescent period involves the recovery from the infection. The signs and symptoms disappear, and the person returns to a healthy state. However, depending on the type of infection, there may be a temporary or permanent change in the patient's previous health state even after the convalescent period.

incubation period

The incubation period is the interval between the pathogen's invasion of the body and the appearance of symptoms of infection. During this stage, the organisms are growing and multiplying.

inflammatory response

The inflammatory response is a protective mechanism that eliminates the invading pathogen and allows for tissue repair to occur. Inflammation helps the body to neutralize, control, or eliminate the offending agent and to prepare the site for repair

Full Stage of Illness

The presence of infection-specific signs and symptoms indicates the full stage of illness.

Time frame for influenza

Transmitted 1-2 days before onset of symptoms & 4-5 days after onset of symptoms

Vesicular Sounds

Difference between vesicular sounds and crackle sounds

Vesicular breath sounds are normal and described as low-pitched, soft sounds over the lungs' peripheral fields. Crackles are soft, high-pitched, discontinuous popping sounds heard on inspiration.

Which guideline describes the proper method for measuring the appropriate length to use when inserting a nasopharyngeal airway? When holding the airway on the side of the client's face, it should reach from the tragus of the ear to the tip of the nostril. When holding the airway on the side of the client's face, it should reach from the opening of the mouth to the back angle of the jaw. When holding the airway on the side of the client's face, it should reach from the tip of the ear to the nostril times two. The airways come in standard sizes determined by the height and weight of the client.
