Adult Health Nursing Quizlet Final

Correct Answer: A

Rationale: Breastfeeding is actually a protective factor against acute otitis media (AOM) in children due to the antibodies and nutrients present in breast milk that help strengthen the immune system and the Eustachian tube function. Swimming, exposure to cigarette smoke, and poor hygiene are all risk factors for AOM. Swimming can introduce water into the ears, which can lead to infections. Exposure to cigarette smoke can irritate the mucous membranes in the respiratory tract and increase the risk of infections. Poor hygiene can lead to the spread of bacteria that can cause AOM.

Correct Answer: C

Rationale: When discharging a suicidal patient who has been taking tricyclic antidepressant drugs, it is crucial for the nurse to evaluate the risk for suicide by overdose of the medication. Tricyclic antidepressants have a narrow therapeutic index, meaning that the difference between a therapeutic dose and a toxic dose can be quite small. This makes them particularly dangerous in cases of overdose, as they can lead to severe toxic effects, including cardiac arrhythmias, seizures, and death.

Correct Answer: B

Rationale: Thrombotic thrombocytopenic purpura (TTP) is a rare blood disorder characterized by microangiopathic hemolytic anemia, thrombocytopenia, fever, neurological abnormalities, and renal dysfunction. The peripheral blood smear in TTP typically shows fragmented red blood cells (schistocytes) due to mechanical destruction within small blood vessels. Laboratory findings in TTP commonly include elevated lactate dehydrogenase (LDH), decreased haptoglobin (as it is consumed in the clearance of free hemoglobin), and increased indirect bilirubin due to increased red blood cell breakdown. This combination of clinical presentation and laboratory abnormalities is classic for TTP. Hemolytic uremic syndrome (HUS) may present similarly but is more commonly associated with renal dysfunction and is often triggered by infection with Shiga toxin-producing E. coli.

Correct Answer: A

Rationale: A safe patient environment should address the physical, emotional, and psychological well-being of the patient. While socio-economic needs are important for overall patient care, they are not directly related to creating a safe environment within a healthcare setting. Factors such as maintaining sanitation, meeting basic needs, and reducing physical hazards are crucial to ensuring the safety and well-being of patients. However, addressing socio-economic needs falls more within the realm of holistic patient care beyond just the physical safety aspect.

Correct Answer: C

Rationale: Feedback is an essential indicator of effective communication because it allows the sender to understand how the message was received by the receiver. It provides an opportunity to clarify any misunderstandings, confirm understanding, and ensure that the communication has been successful. Without feedback, the sender cannot be sure if their message was accurately understood or if further explanation or clarification is needed. Effective communication involves a two-way exchange, and feedback plays a crucial role in ensuring that the message is effectively transmitted and received.
