1. What do crackles heard on lung auscultation indicate?
- A. Cyanosis.
- B. Bronchospasm.
- C. Airway narrowing.
- D. Fluid-filled alveoli.
Correct answer: D
Rationale: Crackles heard on lung auscultation are caused by the popping open of small airways that are filled with fluid. This is commonly associated with conditions such as pulmonary edema, pneumonia, or heart failure. Cyanosis (Choice A) is a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood, not directly related to crackles. Bronchospasm (Choice B) refers to the constriction of the airway smooth muscle, causing difficulty in breathing but does not typically produce crackles. Airway narrowing (Choice C) can lead to wheezing but is not directly linked to crackles heard on auscultation.
2. Which of the following best describes the nurse's responsibility in obtaining informed consent?
- A. The nurse is responsible for ensuring that the patient understands the procedure and has the opportunity to ask questions.
- B. The nurse should ensure that the patient signs the consent form before the procedure begins.
- C. The nurse is responsible for witnessing the patient sign the consent form and documenting the event.
- D. The nurse should delegate the task of obtaining informed consent to another healthcare provider.
Correct answer: A
Rationale: The correct answer is A. Informed consent is a process where the healthcare provider, in this case, the nurse, ensures that the patient understands the procedure, risks, benefits, and alternatives before they agree to it. The nurse plays a crucial role in facilitating this understanding by explaining the information in a clear and understandable manner and providing the patient with the opportunity to ask questions. Choice B is incorrect because merely obtaining the patient's signature on the consent form does not ensure that the patient truly understands what they are consenting to. Choice C is not fully accurate as the nurse's role goes beyond just witnessing the signature; it involves actively ensuring the patient's comprehension. Choice D is incorrect as the responsibility of obtaining informed consent should not be delegated to another healthcare provider, as it is the nurse's duty to ensure proper communication and understanding with the patient.
3. A client who has received sodium bicarbonate in large amounts is at risk for metabolic alkalosis. For which of the following signs and symptoms does the nurse assess this client?
- A. Disorientation and dyspnea
- B. Drowsiness, headache, and tachypnea
- C. Tachypnea, dizziness, and paresthesias
- D. Dysrhythmias and decreased respiratory rate and depth
Correct answer: D
Rationale: The correct answer is D. A client with metabolic alkalosis may present with dysrhythmias and a decreased respiratory rate and depth as the body tries to compensate by retaining carbon dioxide. Options A, B, and C do not typically correlate with the signs and symptoms of metabolic alkalosis. Disorientation, dyspnea, drowsiness, headache, tachypnea, dizziness, and paresthesias are not commonly associated with metabolic alkalosis. Therefore, they are incorrect choices.
4. An overweight client taking warfarin (Coumadin) has dry skin due to decreased arterial blood flow. What should the nurse instruct the client to do? Select all that apply.
- A. Apply lanolin or petroleum jelly to intact skin.
- B. Follow a reduced-calorie, reduced-fat diet.
- C. Inspect the involved areas daily for new ulcerations.
- D. Instruct the client to limit activities of daily living (ADLs).
Correct answer: A
Rationale: To address dry skin and prevent chronic ulcers and infections in an overweight client on warfarin with decreased arterial blood flow, the nurse should instruct the client to apply lanolin or petroleum jelly to intact skin. This helps maintain skin integrity and moisture. Following a reduced-calorie, reduced-fat diet (Choice B) may be beneficial for weight management but is not directly related to skin care. Inspecting involved areas daily for new ulcerations (Choice C) is important for skin assessment and early intervention but does not specifically address dry skin. Instructing the client to limit activities of daily living (ADLs) (Choice D) is not necessary for addressing dry skin; in fact, promoting mobility and circulation through appropriate activities is crucial.
5. A 26-year-old female client is admitted to the hospital for treatment of a simple goiter, and levothyroxine sodium (Synthroid) is prescribed. Which symptoms indicate to the nurse that the prescribed dosage is too high for this client?
- A. Palpitations and shortness of breath
- B. Bradycardia and constipation
- C. Lethargy and lack of appetite
- D. Muscle cramping and dry, flushed skin
Correct answer: A
Rationale: The correct answer is A. An overdose of thyroid preparation generally manifests symptoms of an agitated state such as tremors, palpitations, shortness of breath, tachycardia, increased appetite, agitation, sweating, and diarrhea. Palpitations and shortness of breath are signs of excessive thyroid medication. Choices B, C, and D are incorrect symptoms for a dosage that is too high. Bradycardia and constipation, lethargy and lack of appetite, muscle cramping and dry, flushed skin are more indicative of hypothyroidism or an insufficient dosage of levothyroxine.
