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. A client complained of nausea, a metallic taste in her mouth, and fine hand tremors 2 hours after her first dose of lithium carbonate (Lithane). What is the nurse's best explanation of these findings?
- A. These side effects are common and should subside in a few days.
- B. The client is probably having an allergic reaction and should discontinue the drug.
- C. Taking the lithium on an empty stomach should decrease these symptoms.
- D. Decreasing dietary intake of sodium and fluids should minimize the side effects.
Correct answer: A
Rationale: The correct answer is, 'These side effects are common and should subside in a few days.' Nausea, metallic taste, and fine hand tremors are common side effects of lithium carbonate (Lithane) and typically diminish within a few days as the body adjusts to the medication. Option B is incorrect because these symptoms are not indicative of an allergic reaction. Option C is incorrect as taking lithium on an empty stomach does not directly address or decrease these specific side effects. Option D is also incorrect as reducing sodium and fluid intake is not the recommended approach to managing these particular side effects of lithium.
3. A client has developed a vitamin C deficiency. Which of the following symptoms might the nurse most likely see with this condition?
- A. Cracks at the corners of the mouth
- B. Altered mental status
- C. Bleeding gums and loose teeth
- D. Anorexia and diarrhea
Correct answer: C
Rationale: A client with a severe vitamin C deficiency has a condition called scurvy. Scurvy is characterized by symptoms such as bleeding gums, loose teeth, poor wound healing, and easy bruising. The correct answer is 'Bleeding gums and loose teeth' because these are classic signs of scurvy due to vitamin C deficiency. Choice A ('Cracks at the corners of the mouth') is more indicative of a deficiency in B vitamins, specifically riboflavin. Choice B ('Altered mental status') is not typically associated with vitamin C deficiency but can occur with other conditions like vitamin B12 deficiency. Choice D ('Anorexia and diarrhea') are not common symptoms of vitamin C deficiency, as they are more commonly associated with other gastrointestinal issues or deficiencies in different nutrients.
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 patient with Glaucoma is verbalizing his daily medication routine to the nurse. He states he has two different eye drop medications, both every twelve hours. He washes his hands, instills the drops, closes his eyes gently, and presses his finger to the corner of his eye nearest his nose. After waiting 1 minute with his eyes closed, he instills the other medication in the same way. What is the nurse's best response?
- A. ''You should wait more than 1 minute between different medications.''
- B. ''Your routine is very good! Can you demonstrate it for me?''
- C. ''It is actually not the best practice to close your eyes after instilling eye drops.''
- D. ''You should actually be pressing your finger in the other corner of the eye.''
Correct answer: A
Rationale: It is recommended to wait 10-15 minutes between different eye drop medications to give them time to absorb and avoid one medication washing another one out. Choice A is the correct response as the patient should wait more than 1 minute between administering different eye drop medications. Choice B is incorrect as the routine described by the patient needs improvement. Choice C is inaccurate as closing the eyes after instilling eye drops is a best practice to ensure proper absorption. Choice D is incorrect as pressing the finger to the corner of the eye nearest the nose is the correct technique.
