Nursing Elites

1. What is the primary purpose of handwashing?

• A. To promote hand circulation
• B. To prevent the transfer of microorganisms
• C. To avoid touching the client with a dirty hand
• D. To provide comfort

Correct answer: B

Rationale: The primary purpose of handwashing is to prevent the transfer of microorganisms. Proper hand hygiene helps reduce the risk of spreading harmful bacteria and viruses, thus promoting overall health and preventing infections. Choice A is incorrect as handwashing primarily focuses on cleanliness rather than promoting circulation. Choice C is incorrect as it implies that the main concern is avoiding client discomfort rather than preventing infection. Choice D is incorrect as while handwashing can be comforting in some situations, its primary purpose is not to provide comfort but to maintain hygiene.

2. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

3. A group of clients are being educated about influenza. Which of the following client statements indicates an understanding of the teaching?

• A. ''I should wash my hands after blowing my nose to prevent spreading the virus.''
• B. ''I need to avoid drinking fluids if I develop symptoms.''
• C. ''I need a flu shot every 2 years because of the different flu strains.''
• D. ''I should cover my mouth with my hand when I sneeze.''

Correct answer: A

Rationale: The correct answer is, 'I should wash my hands after blowing my nose to prevent spreading the virus.' This statement shows understanding of the importance of hand hygiene in preventing the spread of influenza. Washing hands after activities like blowing the nose can help reduce the risk of transmitting the virus to others. Choices B, C, and D are incorrect as they do not reflect accurate understanding of influenza prevention measures.

4. When reviewing the prescriptions for a client with a pneumothorax, which of the following actions should the nurse perform first?

• A. Assess the client's pain.
• B. Obtain a large-bore IV needle for decompression.
• C. Administer lorazepam.
• D. Prepare for chest tube insertion.

Correct answer: B

Rationale: In a client with a pneumothorax, the priority action for the nurse is to obtain a large-bore IV needle for decompression. This intervention helps to relieve the pressure in the pleural space, allowing the lung to re-expand. Prompt decompression is crucial in managing a tension pneumothorax, which can be life-threatening. Assessing pain, administering medication, and preparing for chest tube insertion are important, but they should follow the immediate intervention of decompression in a critical situation like a tension pneumothorax.

5. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.
