1. Which of the following is the best position for a patient experiencing dyspnea?
- A. Supine position.
- B. Fowler's position.
- C. Trendelenburg position.
- D. Lateral recumbent position.
Correct answer: B
Rationale: Fowler's position is the best position for a patient experiencing dyspnea. This position involves sitting the patient upright with the head of the bed elevated between 45-60 degrees. Fowler's position helps improve breathing in patients with dyspnea by promoting lung expansion, aiding in better oxygenation, and reducing the work of breathing. The supine position (Choice A) may worsen dyspnea by limiting lung expansion. The Trendelenburg position (Choice C) with the feet elevated and the head down is not recommended for dyspnea as it can increase pressure on the chest and compromise breathing. The lateral recumbent position (Choice D) is not ideal for dyspnea as it does not provide optimal lung expansion and may not alleviate breathing difficulty.
2. 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.
3. The nurse is caring for a 70-kg patient who is receiving gentamicin (Garamycin) 85 mg 4 times daily. The patient reports experiencing ringing in the ears. The nurse will contact the provider to discuss
- A. decreasing the dose to 50 mg QID.
- B. giving the dose 3 times daily.
- C. obtaining a serum drug level.
- D. ordering a hearing test.
Correct answer: C
Rationale: When a patient receiving gentamicin (Garamycin) reports experiencing ringing in the ears, it is crucial to consider the possibility of ototoxicity. Ototoxicity is a known adverse effect of aminoglycosides. The appropriate action for the nurse in this situation is to contact the provider to discuss obtaining a serum drug level. This is important to assess the drug concentration in the patient's blood, which can help determine if the ringing in the ears is related to the medication. Decreasing the dose or changing the dosing frequency without assessing the serum drug level may not address the underlying issue and could potentially lead to suboptimal treatment. Ordering a hearing test may be necessary at a later stage if the serum drug level indicates a concern. Therefore, option C, obtaining a serum drug level, is the most appropriate action to take in this scenario.
4. A 68-year-old client on day 2 after hip surgery has no cardiac history but reports having chest heaviness. The first nursing action should be to:
- A. Inquire about the onset, duration, severity, and precipitating factors of the heaviness.
- B. Administer oxygen via nasal cannula.
- C. Offer pain medication for the chest heaviness.
- D. Inform the physician of the chest heaviness.
Correct answer: A
Rationale: The correct first nursing action when a client reports chest heaviness post-hip surgery is to gather more information through assessment. Inquiring about the onset, duration, severity, and precipitating factors of the heaviness is crucial to determine the cause. This approach helps the nurse to gather essential data to make an informed decision regarding the client's care. Administering oxygen (Choice B) may be indicated based on assessment findings, but it is crucial to assess first. Offering pain medication (Choice C) without further assessment is premature and may mask symptoms. Informing the physician (Choice D) should be done after a thorough assessment to provide comprehensive information for appropriate medical decision-making.
5. A child who weighs 10 kg will begin taking oral trimethoprim-sulfamethoxazole (TMP-SMX). The liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL. The nurse determines that the child’s dose should be 8 mg of TMP and 40 mg of SMX/kg/day divided into two doses. Which order for this child is correct?
- A. 5 mL PO BID
- B. 5 mL PO daily
- C. 10 mL PO BID
- D. 10 mL PO daily
Correct answer: A
Rationale: The correct answer is A: '5 mL PO BID.' To calculate the child’s daily dose requirement, you multiply the child's weight (10 kg) by the prescribed dosage per kg, which is 8 mg for TMP and 40 mg for SMX. This results in a total daily requirement of 80 mg of TMP and 400 mg of SMX. To divide this into two doses, each dose should contain half of the total daily requirement, which is 40 mg TMP and 200 mg SMX. Since the liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL, the correct dose per administration is 5 mL. Therefore, 5 mL PO BID is the correct order. Choice B, '5 mL PO daily,' is incorrect as the total daily dose needs to be divided into two doses. Choices C and D, '10 mL PO BID' and '10 mL PO daily,' respectively, are incorrect as they do not align with the calculated dosage requirements based on the child's weight and the prescribed dosage per kg.
