Nokea
A client in active labor receives a regional anesthetic. Which is the main purpose of regional anesthetics?
- A. To relieve pain by decreasing the client's level of consciousness
- B. To provide general loss of sensation by blocking sensory nerves to an area
- C. To provide pain relief by blocking descending impulses from the central nervous system
- D. To relieve pain by decreasing the perception of pain leading to the pain centers in the brain
Correct Answer: B
Rationale: The correct answer is B: To provide general loss of sensation by blocking sensory nerves to an area. Regional anesthetics work by blocking specific nerve pathways in a targeted area, leading to loss of sensation while maintaining consciousness. This is ideal for laboring clients as it allows pain relief without affecting consciousness or motor function. Choice A is incorrect as regional anesthetics do not aim to decrease consciousness. Choice C is incorrect as regional anesthetics block sensory nerves locally, not descending impulses. Choice D is incorrect as the goal is to block sensation locally, not perception in the brain.

A nurse is caring for a 3-year-old child with strabismus. Which of the following actions should the nurse advise the parents to implement to help prevent amblyopia?
- A. Wear corrective biconcave lenses.
- B. Prevent trauma to the eyes.
- C. Patch the strong eye.
- D. Instill artificial tears.
Correct Answer: C
Rationale: The correct answer is C: Patch the strong eye. Patching the strong eye helps improve vision in the weaker eye, which is essential in preventing amblyopia. By covering the strong eye, the brain is forced to rely on the weaker eye, strengthening its visual acuity. Wearing corrective biconcave lenses may help with refractive errors but does not directly address amblyopia prevention. Preventing trauma to the eyes is important for overall eye health but does not specifically target amblyopia prevention. Instilling artificial tears is used for dry eye syndrome and does not play a role in preventing amblyopia.
A nurse is assessing a client who is at 30 wks gestation during a routine prenatal visit. Which of the following findings should the nurse report to the provider?
- A. Swelling of the face
- B. Varicose veins in the calves
- C. Nonpitting 1+ ankle edema
- D. Hyperpigmentation
Correct Answer: A
Rationale: The correct answer is A: Swelling of the face. Facial swelling in a pregnant woman at 30 weeks gestation could be a sign of preeclampsia, a serious condition characterized by high blood pressure and protein in the urine. It is important to report this finding promptly to the provider for further evaluation and management to prevent complications for both the mother and the baby. Varicose veins in the calves (B) and hyperpigmentation (D) are common in pregnancy but are not urgent issues requiring immediate reporting. Nonpitting 1+ ankle edema (C) is a common finding in pregnancy but is not as concerning as facial swelling. Make sure to report any change in the severity of edema.
A nurse is collecting data on a 3-year-old child with eczema in an outpatient center.
- A. "Cover the crib mattress with a plastic cover."'
- B. "Give the child a bubble bath for 20 min each day."'
- C. "Place a humidifier in the child's room."'
- D. "Dress the child in warm wool clothing in cold weather."'
Correct Answer: C
Rationale: The correct answer is C, "Place a humidifier in the child's room." This is because eczema can worsen with dry skin, and a humidifier can help maintain moisture in the air, preventing skin dryness. Choice A is incorrect as a plastic cover can trap heat and sweat, exacerbating eczema. Choice B is incorrect as bubble baths can irritate sensitive skin. Choice D is incorrect as wool clothing can be abrasive and trigger eczema flare-ups.
A client at 33 weeks gestation is admitted for suspected abruptio placenta. Which factor in the client's history supports this diagnosis? The client states that she:
- A. drinks two glasses of wine before dinner every night.
- B. has intermittent contractions that are relieved by walking.
- C. had intercourse with her partner last night.
- D. used crack an hour before the symptoms began.
Correct Answer: D
Rationale: The correct answer is D: used crack an hour before the symptoms began. Abruptio placenta is a condition where the placenta prematurely separates from the uterine wall. Substance abuse, such as crack cocaine, can lead to vasoconstriction and increased risk of abruptio placenta due to compromised blood flow to the placenta. This can result in fetal distress and maternal bleeding. The other choices (A, B, C) do not directly correlate with abruptio placenta. Intermittent contractions relieved by walking are more suggestive of Braxton Hicks contractions, intercourse is not a known risk factor for abruptio placenta, and drinking wine does not typically cause this condition.
Which site is preferred for giving an IM injection to a newborn?
- A. Ventrogluteal
- B. Vastus lateralis
- C. Rectus femoris
- D. Dorsogluteal
Correct Answer: B
Rationale: The correct answer is B: Vastus lateralis. The vastus lateralis muscle is preferred for IM injections in newborns due to its large muscle mass, minimal risk of injury to major blood vessels and nerves, and easy accessibility. It is also recommended by healthcare guidelines for infants. Ventrogluteal and dorsogluteal sites are not recommended for newborns due to the risk of damaging nerves and blood vessels. The rectus femoris muscle is not typically used for IM injections in newborns as it is less accessible and has a higher risk of injury.
