1. What is an important nursing responsibility when a dysrhythmia is suspected?
- A. order an immediate electrocardiogram
- B. count the radial pulse every 1 minute for five times
- C. count the apical pulse for 1 full minute, and compare the rate with the radial pulse rate
- D. have someone else take the radial pulse simultaneously with the apical pulse
Correct answer: C
Rationale: When a dysrhythmia is suspected, an important nursing responsibility is to count the apical pulse for 1 full minute and then compare this rate with the radial pulse rate. This method helps in identifying dysrhythmias as it allows for a direct comparison of the heart's rhythm at two different pulse points. Ordering an immediate electrocardiogram (Choice A) may be necessary but should not be the first step. Counting the radial pulse multiple times (Choice B) is not as accurate as comparing rates directly. Having someone else take the radial pulse simultaneously (Choice D) may introduce errors and inconsistencies in the measurement.
2. An order is written for an isotonic enema for a 2-year-old child. What is the maximum amount of fluid the nurse should administer without a specific order from the healthcare provider?
- A. 100 to 150 mL
- B. 155 to 250 mL
- C. 255 to 360 mL
- D. 365 to 500 mL
Correct answer: B
Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL. This range is considered safe to prevent overdistension and potential harm to the child's rectum. Choices A, C, and D exceed the safe range for a 2-year-old child and can lead to complications such as bowel perforation or electrolyte imbalances.
3. The nurse volunteering at a homeless shelter to assist families with children identifies homelessness as a risk preventing families from achieving positive outcomes in life. What family theory encompasses this approach to assessing family dynamics?
- A. Duvall's developmental theory
- B. Friedman's structural functional theory
- C. Von Bertalanffy's general system theory applied to families
- D. Resiliency model of family stress, adjustment, and adaptation
Correct answer: D
Rationale: The Resiliency model of family stress, adjustment, and adaptation is the appropriate theory in this scenario. This model focuses on identifying risks and protective factors that help families achieve positive outcomes despite challenges. Duvall's developmental theory primarily focuses on family life cycle stages, Friedman's structural functional theory emphasizes the interdependence of family members, and Von Bertalanffy's general system theory applied to families looks at the family as a dynamic system. These theories do not specifically address the concept of resilience and adaptation in the face of stressors like homelessness.
4. Which of the following techniques represents the most appropriate method of opening the airway of an infant with no suspected neck injury?
- A. lift up the chin and hyperextend the neck
- B. tilt the head back without hyperextending the neck
- C. gently lift the chin while maintaining slight flexion of the neck
- D. perform the technique as you would for an older child or adult
Correct answer: B
Rationale: The correct technique for opening the airway of an infant with no suspected neck injury is to tilt the head back without hyperextending the neck. This method helps to keep the airway open without risking injury to the infant's delicate neck structures. Choice A, lifting up the chin and hyperextending the neck, can potentially harm the infant's neck. Choice C, gently lifting the chin while maintaining slight flexion of the neck, is not as effective as tilting the head back. Choice D is incorrect as infants require a different approach compared to older children or adults due to their anatomical differences.
5. An instructor is developing a plan for a class of nursing students on various skin disorders. When describing urticaria, what would the instructor include?
- A. It is a type IV hypersensitivity reaction.
- B. Histamine release leads to vasodilation.
- C. Wheals appear first followed by erythema.
- D. The nonpruritic rash blanches with pressure.
Correct answer: B
Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction, not type IV. When triggered, histamine release leads to vasodilation, causing characteristic wheals. Wheals are typically followed by erythema. The rash in urticaria is pruritic and does blanch with pressure, unlike the nonpruritic rash described in choice D. Therefore, the most appropriate description of urticaria includes histamine release and vasodilation, as stated in choice B.
