What is the disadvantage of local anesthesia?

Correct Answer: D

Rationale: The correct answer is D: pain during injection. Local anesthesia may cause pain during injection due to the needle piercing the skin, which can be uncomfortable for the patient. This is a common disadvantage of local anesthesia. A: Decreased motor function is not a typical disadvantage of local anesthesia as it mainly affects sensory nerves rather than motor nerves. B: Nausea is not a direct side effect of local anesthesia as it does not affect the gastrointestinal system. C: Hypotension is not a common disadvantage of local anesthesia, as it typically does not have a significant impact on blood pressure unless administered in large amounts or combined with other medications that can lower blood pressure.

Correct Answer: C

Rationale: The correct answer is C because nonpharmacologic pain management methods, such as relaxation techniques or massage, do not involve medications that could potentially harm the fetus. This ensures there are no side effects or risks to the fetus during labor. Option A is incorrect as nonpharmacologic pain management does not necessarily guarantee a more rapid labor. Option B is incorrect because while nonpharmacologic methods can provide pain relief, it may not always be more complete compared to pharmacologic options. Option D is incorrect as some nonpharmacologic methods may alter alertness levels, such as hypnosis.

Correct Answer: C

Rationale: The correct answer is C: pudendal. Pudendal nerve block is specifically used to provide anesthesia to the lower vagina and perineum during labor. This block targets the pudendal nerve, which innervates these areas, providing effective pain relief for childbirth. A local anesthetic is more general and may not specifically target the lower vagina and perineum. Epidural anesthesia is typically used to provide pain relief during labor but does not specifically target the lower vagina and perineum. A spinal block provides anesthesia for a larger area including the lower abdomen and legs, not specifically the lower vagina and perineum.

Correct Answer: B

Rationale: The correct answer is B. A patient who delivered a stillborn baby last year is more likely to experience increased anxiety and tension during labor due to previous traumatic experience. This can trigger fear and worry about the current pregnancy outcome, leading to heightened emotional distress. Incorrect Choices: A: Refusing medication does not necessarily correlate with increased anxiety during labor. C: Not attending childbirth classes may result in lack of knowledge but does not directly relate to increased anxiety during labor. D: Having two children younger than 3 years may cause stress but does not specifically indicate increased anxiety during labor.

Correct Answer: A

Rationale: The correct answer is A: imagery. Imagery involves creating mental pictures or sensations to help focus and relax the mind. In this scenario, the laboring patient visualizes her body opening to facilitate the birthing process, which can help reduce anxiety and pain perception. Effleurage (B) is a massage technique, dissociation (C) is a coping strategy to mentally detach from pain, and distraction (D) involves diverting attention away from pain stimuli. However, in this case, the patient's focus on visualizing the birthing process aligns with the use of imagery.
