Nursing Elites

1. The practical nurse is caring for a client whose urine drug screen is positive for cocaine. Which behavior is this client likely to exhibit during cocaine withdrawal?

• A. Elevated energy level
• B. Euphoria
• C. High self-esteem
• D. Powerful craving for more

Correct answer: D

Rationale: The correct answer is D: Powerful craving for more. During cocaine withdrawal, individuals often experience intense cravings for the drug, along with symptoms such as fatigue, depression, and anxiety. These cravings can be overpowering and lead to a strong desire to seek out more cocaine to alleviate the withdrawal symptoms. Choices A, B, and C are incorrect as elevated energy level, euphoria, and high self-esteem are more associated with the effects of cocaine rather than withdrawal symptoms. Withdrawal from cocaine is characterized by the opposite, such as fatigue, low mood, and intense cravings.

2. Which hormone is primarily responsible for the regulation of calcium and phosphate in the blood?

• A. Parathyroid hormone
• B. Insulin
• C. Cortisol
• D. Thyroxine

Correct answer: A

Rationale: Parathyroid hormone is the correct answer. It regulates calcium and phosphate levels in the blood by increasing calcium reabsorption in the kidneys and releasing calcium from bones. Insulin is involved in glucose metabolism, not calcium and phosphate regulation. Cortisol is a stress hormone and is not primarily responsible for regulating calcium and phosphate levels. Thyroxine is a thyroid hormone that primarily regulates metabolism, not calcium and phosphate in the blood.

3. According to the principle of asepsis, which situation should the PN consider to be sterile?

• A. A one-inch border around the edges of a sterile field set up in the operating room
• B. A sterile glove that the PN thinks might have touched hair
• C. A wrapped, unopened sterile 4x4 gauze pad placed on a damp table top
• D. An open sterile Foley catheter kit set up on a table at the PN's waist level

Correct answer: A

Rationale: According to the principle of asepsis, the one-inch border around the edges of a sterile field set up in the operating room is considered non-sterile, while the central area remains sterile. Therefore, the PN should consider the situation described in choice A to be sterile. Choice B is incorrect because a glove that may have touched hair is contaminated. Choice C is incorrect as a sterile item placed on a damp surface is considered contaminated. Choice D is incorrect as a sterile kit set up at the PN's waist level is prone to contamination.

4. The HCP gives a pregnant woman a prescription for one prenatal vitamin with iron daily and tells her that she needs to increase foods in her diet because her hemoglobin is 8.2 grams/dL. When a list of iron-rich foods is given to the client, she tells the PN that she is a vegetarian and does not eat anything that "bleeds." Which instruction should the PN provide?

• A. All below
• B. Increase green leafy vegetables in the diet
• C. Oatmeal is a good choice for breakfast
• D. Add lentils and black beans to soup

Correct answer: A

Rationale: Vegetarians can increase their iron intake through plant-based sources such as green leafy vegetables, oatmeal, and legumes, which are rich in iron.

5. While performing an inspection of a client's fingernails, the PN observes a suspected abnormality of the nail's shape and character. Which finding should the PN document?

• A. Clubbed nails
• B. Splinter hemorrhages
• C. Longitudinal ridges
• D. Koilonychia or spoon nails

Correct answer: A

Rationale: The correct answer is A: Clubbed nails. Clubbed nails are a significant finding often associated with chronic hypoxia or lung disease. The presence of clubbed nails should be documented for further evaluation. Splinter hemorrhages (Choice B) are tiny areas of bleeding under the nails and are associated with conditions like endocarditis. Longitudinal ridges (Choice C) are common and often a normal finding in older adults. Koilonychia or spoon nails (Choice D) refer to nails that are concave or scooped out, often seen in conditions like iron deficiency anemia or hemochromatosis. These conditions are not typically associated with chronic hypoxia or lung disease, making them less likely findings in this situation.
