Nursing Elites

1. When medications have an additive, synergistic, or antagonistic effect on a tissue, a ________ reaction has occurred.

• A. pharmaceutical
• B. pharmacodynamic
• C. pharmacokinetic
• D. drug incompatibility

Correct answer: B

Rationale: The correct answer is 'pharmacodynamic.' Pharmacodynamics pertain to the effect of a drug on receptors, explaining how drugs affect tissues. Pharmaceutical reactions refer to chemical reactions between drugs before administration or absorption, not their effect on tissues. Pharmacokinetic reactions involve how the body affects the drug, not the tissue. Drug incompatibilities are essentially pharmaceutical reactions, not the specific effects on tissues seen in pharmacodynamic reactions.

2. Ashley and her boyfriend Chris, both 19 years old, are transported to the Emergency Department after being involved in a motorcycle accident. Chris is badly hurt, but Ashley has no apparent injuries, though she appears confused and has trouble focusing on what is going on around her. She complains of dizziness and nausea. Her pulse is rapid, and she is hyperventilating. The nurse should assess Ashley's level of anxiety as:

• A. mild.
• B. moderate.
• C. severe.
• D. panic.

Correct answer: C

Rationale: Explanation: Ashley is displaying symptoms of severe anxiety, including confusion, trouble focusing, dizziness, nausea, rapid pulse, and hyperventilation. These somatic symptoms, along with changes in vital signs, indicate severe anxiety. In severe anxiety, individuals are unable to solve problems and have a poor grasp of their environment. On the other hand, mild anxiety may lead to mild discomfort or even enhanced performance, while moderate anxiety results in difficulty grasping information and minor changes in vital signs. Panic, the most severe level of anxiety, involves markedly disturbed behavior and a potential loss of touch with reality. Therefore, based on Ashley's symptoms, her anxiety level should be assessed as severe.

3. To decrease a client's use of denial and increase the client's expression of feelings, what should the nurse do?

• A. Tell the client to stop using the defense mechanism of denial
• B. Positively reinforce each expression of feelings
• C. Instruct the client to express feelings
• D. Challenge the client each time denial is used

Correct answer: B

Rationale: The most appropriate approach to decrease a client's use of denial and promote the expression of feelings is to positively reinforce each expression of feelings. This method helps the client feel supported and validated, encouraging them to continue expressing their emotions openly. Positively reinforcing the expression of feelings can help reduce the need for denial as the client learns that their emotions are acknowledged and accepted. Choices A, C, and D are incorrect. Choice A of telling the client to stop using denial is too directive and may be ineffective. Instructing the client to express feelings (Choice C) lacks positive reinforcement, and challenging the client each time denial is used (Choice D) can create a confrontational environment that hinders therapeutic progress.

4. A nurse is teaching the mother of an 11-month-old infant how to clean the infant's teeth. The nurse tells the mother to take which action?

• A. Use a small amount of toothpaste and a soft-bristle toothbrush
• B. Use water and a cotton swab and rub the teeth
• C. Use diluted fluoride and rub the teeth with a soft washcloth
• D. Dip the infant's pacifier in maple syrup so that the infant will suck

Correct answer: C

Rationale: The correct action when cleaning an infant's teeth is to use water and a cotton swab to gently rub the teeth. This method helps in removing any food particles or plaque buildup without the risks associated with toothpaste ingestion. Using a small amount of toothpaste and a soft-bristle toothbrush is not recommended for infants as they may swallow the toothpaste, leading to potential fluoride ingestion issues. Using diluted fluoride and rubbing the teeth with a soft washcloth is unnecessary at this age since infants typically receive fluoride through other sources like formula. Dipping the infant's pacifier in maple syrup is highly inappropriate and poses a significant risk of tooth decay due to the high sugar content, which can harm the infant's teeth.

5. The new mother asks why her baby has lost weight since he was born. The best explanation of the weight loss is:

• A. The baby is dehydrated due to polyuria.
• B. The baby is hypoglycemic due to lack of glucose.
• C. The baby is allergic to the formula the mother is giving him.
• D. The baby can lose up to 10% of weight due to meconium stool, loss of extracellular fluid, and initiation of breastfeeding.

Correct answer: D

Rationale: After birth, newborns can lose weight due to meconium stool, loss of extracellular fluid, and the initiation of breastfeeding. This weight loss is a normal and expected physiological process, and infants can lose up to 10% of their birth weight during this period. There is no indication of dehydration (polyuria), hypoglycemia (lack of glucose), or allergy to the formula as reasons for weight loss in newborns. Therefore, answers A, B, and C are incorrect. Answer D provides the most accurate explanation for the observed weight loss in the newborn.
