1. Which neurotransmitter is most closely associated with mood regulation and is targeted by antidepressants?

• A. Serotonin
• B. Dopamine
• C. GABA
• D. Acetylcholine

Correct answer: A

Rationale: The correct answer is A: Serotonin. Serotonin plays a vital role in mood regulation, and its imbalance is often associated with depression. Many antidepressants function by boosting serotonin levels in the brain. Dopamine (Choice B) is more linked to reward and pleasure pathways in the brain, not primarily targeted for mood regulation. GABA (Choice C) is an inhibitory neurotransmitter that helps reduce neuronal excitability, not primarily associated with mood regulation. Acetylcholine (Choice D) is involved in muscle movement and cognitive functions, not the primary target of antidepressants for mood regulation.

2. A 50-year-old female is in the hospital with peripheral artery disease. In the nursing care plan, the nurse lists the following nursing diagnosis: Ineffective tissue perfusion: peripheral related to venous stasis. Which of the following would not be an appropriate nursing action to list in the implementation of this diagnosis?

• A. Keep the client's extremities cold
• B. Check for strength and symmetry of peripheral pulses
• C. Keep the client's legs elevated
• D. Monitor for any constrictions, such as clothes or covers that are too tight around the legs

Correct answer: A

Rationale: Keeping the client’s extremities cold would worsen perfusion issues and is not recommended. In peripheral artery disease, maintaining warmth is crucial to promote vasodilation and improve blood flow. Checking peripheral pulses for strength and symmetry, keeping the client's legs elevated to reduce venous stasis, and monitoring for constrictions that may impair circulation are appropriate nursing actions to enhance tissue perfusion in this case. Thus, option A is incorrect as it would hinder perfusion in the affected extremities.

3. At what age does a 9-year-old child typically lose which of the following teeth?

• A. Central incisor
• B. Second molar
• C. Lateral incisor
• D. Cuspid

Correct answer: A

Rationale: A 9-year-old child typically loses their central incisors, not the lateral incisors or second molars. The central incisors are usually among the first teeth that children lose around 6 to 7 years of age, as part of the natural process of shedding primary teeth to make way for permanent teeth. The second molars and cuspids are typically lost later in the mixed dentition phase. Therefore, option A, 'Central incisor,' is the correct answer.

4. A female client taking a liquid iron preparation expresses concern that her tooth color has darkened since starting the medication. What action should the PN implement?

• A. Teach the client to use a straw when taking the medication to reduce further tooth staining
• B. Advise the client to withhold further doses until consulting with the healthcare provider
• C. Reassure the client that this change indicates the medication is having the desired effect
• D. Determine if the client is also experiencing mouth or gum pain and difficulty swallowing

Correct answer: A

Rationale: The correct action for the PN to implement is to teach the client to use a straw when taking the medication to reduce further tooth staining. Using a straw minimizes contact between the iron preparation and the teeth, helping prevent additional staining. Choice B is incorrect because withholding doses without consulting the healthcare provider could be detrimental to the client's health. Choice C is incorrect because darkening of tooth color is not an expected effect of liquid iron preparation and should not be reassured as a desired effect. Choice D is incorrect as it does not directly address the client's concern about tooth staining.

5. During a clinic visit for a sore throat, a client's basal metabolic panel reveals a serum potassium of 3.0 mEq/L. Which intervention should the PN recommend to the client based on this finding?

• A. Increase intake of dried peaches and apricots
• B. Reduce intake of red meats
• C. Encourage use of a soft toothbrush
• D. Force fluid intake to 1500 mL daily

Correct answer: A

Rationale: The correct answer is to recommend increasing the intake of dried peaches and apricots. A serum potassium level of 3.0 mEq/L is considered low. Increasing the intake of potassium-rich foods can help raise the serum potassium level, preventing complications such as muscle weakness and cardiac arrhythmias. Choice B, reducing intake of red meats, is incorrect because red meats are not specifically related to potassium levels. Choice C, encouraging the use of a soft toothbrush, is unrelated to addressing low potassium levels. Choice D, forcing fluid intake to 1500 mL daily, is not the appropriate intervention for low serum potassium; instead, increasing potassium-rich foods is more beneficial.
