Nursing Elites

1. The client has an order for 0.45 mg of Diltiazem. The medication vial has a concentration of 3 mg/mL. How many mL of the drug should be administered?

• A. 0.15 mL
• B. 6.6 mL
• C. 1.5 mL
• D. 0.65 Ml

Correct answer: A

Rationale: To calculate the amount of drug to be administered, divide the ordered dose by the concentration of the medication in the vial. In this case, 0.45 mg � 3 mg/mL = 0.15 mL. Therefore, the correct answer is 0.15 mL. Choice B (6.6 mL) is incorrect as it does not result from the correct calculation. Choice C (1.5 mL) is incorrect as it is not the result of dividing the ordered dose by the concentration. Choice D (0.65 mL) is incorrect as it is not the accurate calculation based on the provided information.

2. When inspecting the ears for cerumen impaction, the nurse checks for which finding?

• A. Redness and swelling of the tympanic membrane
• B. An external auditory canal that is longer than normal
• C. The presence of edema in the external auditory canal
• D. A yellowish or brownish waxy material in the external auditory canal

Correct answer: D

Rationale: When inspecting the ears for cerumen impaction, the nurse should look for a yellowish or brownish waxy material in the external auditory canal. Cerumen, also known as ear wax, is a secretion that can become impacted due to various reasons. It is produced by the vestigial apocrine sweat glands in the external ear canal. Cerumen may partially obscure the eardrum or totally occlude the ear canal. The other options, redness and swelling of the tympanic membrane, an external auditory canal that is longer than normal, and the presence of edema in the external auditory canal, are not indicative findings of cerumen impaction.

3. An assessment of the skull of a normal 10-month-old baby should identify which of the following?

• A. closure of the posterior fontanel.
• B. closure of the anterior fontanel.
• C. overlap of cranial bones.
• D. ossification of the sutures.

Correct answer: B

Rationale: The correct answer is the closure of the anterior fontanel. By 10 months of age, the anterior fontanel should be closed. The posterior fontanel should actually close by the age of 2 months, making choice A incorrect. Overlap of cranial bones is not a typical finding in a normal 10-month-old baby's skull, so choice C is incorrect. Ossification of the sutures is an ongoing process in skull development and should not be a definitive indicator at this age, making choice D incorrect.

4. A nurse assisting with data collection plans to perform the Romberg test. After describing the test to the client, the nurse tells the client that it will help reveal which disorder?

• A. Loss of hearing acuity
• B. A problem with balance
• C. A problem with distant hearing
• D. A problem discriminating high-pitched and low-pitched sounds

Correct answer: B

Rationale: The Romberg test is a balance assessment that evaluates cerebellar function. During the test, the client stands with feet together and eyes closed, aiming to maintain balance for about 20 seconds. This test helps identify issues related to balance and proprioception, not hearing acuity or sound discrimination. Choices C and D are incorrect as the Romberg test focuses on balance, not distant hearing or sound discrimination.

5. When a couple experiencing infertility presents for a fertility workup, which of the following procedures should the nurse prepare the couple to have first?

• A. Hysterosalpingography
• B. Semen analysis
• C. Endometrial biopsy
• D. Transvaginal ultrasound

Correct answer: B

Rationale: Semen analysis is the most appropriate initial diagnostic test for a couple experiencing infertility. It is the least invasive of the listed tests, and since male factor infertility contributes to around 35% of cases, assessing semen parameters early is crucial. Hysterosalpingography is a radiographic test to evaluate tubal patency and uterine cavity abnormalities. Endometrial biopsy assesses endometrial receptivity post-ovulation. Transvaginal ultrasound is mainly used in infertility treatment to monitor follicle development, oocyte maturity, and luteal phase defects. Choices A, C, and D are more invasive, require specialized expertise, and are costlier. If semen analysis yields normal results, further tests may be warranted.
