Nursing Elites

1. Mobility is an important human function. The hazards of immobility lead to many physical and emotional problems. Immobility can lead to detrimental cardiac, muscular, respiratory, skeletal, urinary, gastrointestinal, skin, and emotional changes. Which of the following is an example of a skeletal hazard of immobility?

• A. Contractures.
• B. Constipation.
• C. Calcium loss.
• D. Catabolism.

Correct answer: C

Rationale: All choices are hazards of immobility, but only calcium loss from the bones is a skeletal system impairment that results from immobility. Contractures are muscle shortening due to prolonged positioning, which affects the muscular system. Constipation is a gastrointestinal issue. Catabolism is a metabolic process, not specific to the skeletal system.

2. Asepsis is defined as ________________.

• A. the absence of all microorganisms
• B. the absence of disease-causing germs
• C. a urinary infection
• D. a pathogenic infection

Correct answer: B

Rationale: Asepsis is defined as the absence of disease-causing germs. It is surgical asepsis that is defined as the absence of all microorganisms, including spores. A pathogenic infection is an invasion of the body by a pathogen, or disease-causing germ, and a urinary infection is only one type of infection.

3. While caring for a client in labor, a nurse attaches an electronic fetal monitor to the client's abdomen to assess the baby's heart rate. The nurse observes that the baby's heart rate slows down during each contraction and does not return to normal limits until after the contraction is complete. What type of fetal heart rate change does this pattern describe?

• A. Variable decelerations
• B. Late decelerations
• C. Early decelerations
• D. Accelerations

Correct answer: B

Rationale: Late decelerations are characterized by the baby's heart rate declining in utero during contractions. The heart rate drops below baseline and stays low until after the contraction ends. Late decelerations are concerning as they indicate uteroplacental insufficiency, which can compromise fetal oxygenation. This pattern is a non-reassuring sign and requires immediate intervention. Variable decelerations are typically abrupt decreases in heart rate, often associated with cord compression. Early decelerations, on the other hand, mirror the contractions and are considered benign, resulting from fetal head compression. Accelerations are reassuring signs of fetal well-being, indicating a responsive and healthy fetal nervous system.

4. A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?

• A. Uncompensated respiratory acidosis
• B. Compensated respiratory alkalosis
• C. Uncompensated metabolic acidosis
• D. Compensated metabolic alkalosis

Correct answer: A

Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.' Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2. Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis. Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.

5. The BRAT diet is often prescribed for patients with gastroenteritis. This acronym stands for:

• A. Bananas, Rice, Applesauce, and Toast
• B. Bread, Rice, Apricots, and Tapioca
• C. Bananas, Rolls, Apricots, and Toast
• D. Bananas, Rolls, Applesauce, and Tapioca

Correct answer: A

Rationale: The BRAT diet, which stands for Bananas, Rice, Applesauce, and Toast, is commonly recommended for patients with gastroenteritis. These easily digestible foods help firm up stools due to their low fiber content and provide essential nutrients lost during vomiting and diarrhea. Choice B is incorrect because it includes apricots, which are not part of the traditional BRAT diet. Choice C is incorrect as it includes rolls, which are not typically included in the BRAT diet. Choice D is incorrect as it includes tapioca, which is not part of the traditional BRAT diet. Therefore, the correct answer is Bananas, Rice, Applesauce, and Toast.
