Health Promotion and Maintenance NCLEX RN Questions
1. A client has started sweating profusely due to intense heat. His overall luid volume is low and he has developed electrolyte imbalance. This client is most likely suffering from:
- A. Malignant hyperthermia
- B. Heat exhaustion
- C. Heat stroke
- D. Heat cramps
Correct answer: B
Rationale: Heat exhaustion occurs when a person has enough diaphoresis that he becomes dehydrated. Intense sweating can cause both luid and electrolyte imbalances. Untreated heat exhaustion can lead to heat stroke, which results in organ damage, loss of consciousness, or death.
2. Which of the following white blood cells is the smallest and can be involved in humoral immunity?
- A. Lymphocyte
- B. Monocyte
- C. Basophil
- D. Erythrocyte
Correct answer: A
Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.
3. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?
- A. A non-rebreather can provide an FiO2 of 40%.
- B. A client should breathe through his or her mouth when using a non-rebreather.
- C. A non-rebreather offers a reservoir from which the client inhales.
- D. The mask of a non-rebreather should be changed every 3 hours.
Correct answer: A
Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.
4. You are caring for an infant who is just about 12 months old. Which assessment data is normal for the infant at this age?
- A. The infant had doubled their birth weight at twelve months.
- B. The infant had tripled their birth weight at twelve months.
- C. The mother reports that the infant is drinking 60 mLs per kilogram of its body weight.
- D. The infant had grown � inch since last month.
Correct answer: A
Rationale: The normal assessment data for the infant at 12 months of age is that the infant has doubled their birth weight at 12 months of age. The mother's reports that the infant is drinking 60 mLs per kilogram of its body weight and the fact that the infant had grown � inch since last month are not normal assessment data. Infants are fed breast milk or formula every two to four hours with a total daily intake of 80 to 100 mLs per kilogram of body weight. As the neonate grows, they gain five to seven ounces during the first six months and then they double their birth weight during the first year; the head circumference increases a half inch each month for six months and then two tenths of an inch until the infant is one year of age. Similarly, the height or length of the newborn increases an inch a month for the first 6 months and then 1/2 inch a month until the infant is 1 year of age.
5. Which of these statements best describes the characteristics of an effective reward feedback system?
- A. Specific feedback is given as close to the event as possible
- B. Staff is given feedback in equal amounts over time
- C. Positive statements precede negative statements
- D. Performance goals should be higher than what is attainable
Correct answer: A
Rationale: The correct answer is that specific feedback should be given as close to the event as possible in an effective reward feedback system. This is important because feedback is most useful when provided immediately. Giving feedback promptly reinforces positive behavior and helps in modifying problem behaviors. Providing feedback close to the event helps in ensuring that standards are clearly understood and can be met. Choices B, C, and D are incorrect because staff should not be given feedback in equal amounts over time, positive statements do not necessarily have to precede negative statements, and setting performance goals higher than what is attainable can lead to demotivation and decreased performance.
