1. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

2. The nurse is caring for a 7-year-old child with glomerulonephritis and is preparing to discuss the plan of care with the parents. In anticipating this encounter, the nurse recognizes that which is a common reaction of parents to the diagnosis of glomerulonephritis?

• A. Fear of the complicated treatment regimen
• B. Anger at the child for requiring hospitalization
• C. Guilt that they did not seek treatment more quickly
• D. Depression that the child may not be able to play sports

Correct answer: C

Rationale: Guilt is a common reaction of parents when their child is diagnosed with glomerulonephritis. Parents often blame themselves for not responding promptly to the child's initial symptoms or feel guilty for not seeking treatment sooner, thinking they could have prevented the development of glomerular damage. While fear of a complicated treatment regimen, anger at the child for hospitalization, and depression about the child not playing sports may be valid concerns, they are generally not as commonly observed as the feeling of guilt among parents in this situation.

3. Which question should the nurse ask the parents of a child suspected of having glomerulonephritis?

• A. Did your child fall off a bike onto the handlebars?
• B. Has the child had persistent nausea and vomiting?
• C. Has the child been itching or had a rash anytime in the last week?
• D. Has the child had a sore throat or a throat infection in the last few weeks?

Correct answer: D

Rationale: Glomerulonephritis refers to a group of kidney disorders characterized by inflammatory injury in the glomerulus. Group A β-hemolytic streptococcal infection is a common cause of glomerulonephritis. Children with glomerulonephritis often develop symptoms after a throat infection caused by streptococcal bacteria. Therefore, asking about a sore throat or throat infection in the last few weeks is crucial to assess the possible link to glomerulonephritis. Choices A, B, and C are not directly associated with the pathophysiology of glomerulonephritis. Asking about falling off a bike, nausea and vomiting, or itching and rash do not provide relevant information for assessing glomerulonephritis in this context.

4. The healthcare provider assesses a patient suspected of having an asthma attack. Which of the following is a common clinical manifestation of this condition?

• A. Audible crackles and orthopnea
• B. An audible wheeze and use of accessory muscles
• C. Audible crackles and use of accessory muscles
• D. Audible wheeze and orthopnea

Correct answer: B

Rationale: Choice B, 'An audible wheeze and use of accessory muscles,' is the correct answer. In asthma, patients commonly present with wheezing due to airway constriction and the use of accessory muscles to aid in breathing. Audible crackles (rales) are more commonly associated with conditions like pneumonia, congestive heart failure, or pulmonary fibrosis. Orthopnea, which is difficulty breathing while lying flat, is typically seen in conditions like heart failure or chronic obstructive pulmonary disease, rather than asthma. Choice C is incorrect as crackles are not a typical finding in asthma. Choice D is incorrect as orthopnea is not a common clinical manifestation of asthma.

5. A man is prescribed lithium to treat bipolar disorder. The nurse is most concerned about lithium toxicity when he notices which of these assessment findings?

• A. The patient states he had a manic episode a week ago
• B. The patient states he has been having diarrhea every day
• C. The patient presents as severely depressed
• D. The patient has a rash and pruritus on his arms and legs

Correct answer: B

Rationale: The correct answer is when the patient states he has been having diarrhea every day. Persistent diarrhea can lead to dehydration, which can increase the risk of lithium toxicity. The other options, such as a manic episode, severe depression, or rash and pruritus, are not directly associated with an increased risk of lithium toxicity.
