Nursing Elites

1. Multifetal pregnancies with triplets occur at a rate of 1 in 8,100 births, but twins occur much more frequently with a rate of:

• A. 1 in 85 births.
• B. 1 in 5400 births.
• C. 1 in 2700 births.
• D. 1 in 540 births

Correct answer: A

Rationale: The correct answer is A: 1 in 85 births. The rate of twin pregnancies is approximately 1 in 85 births. This means that twins are more common compared to triplets, which occur at a rate of 1 in 8,100 births. Choices B, C, and D are incorrect because they do not reflect the correct frequency of twin pregnancies as stated in the question.

2. The doctor has ordered 500 mg of a medication PO once a day. The tablets on hand are labeled as 1 tablet = 250 mg. How many tablets will you administer to your patient?

• A. 1 Tablet
• B. 2 Tablets
• C. 3 Tablets
• D. 4 Tablets

Correct answer: B

Rationale: To calculate the number of tablets needed, divide the total dosage prescribed (500 mg) by the dosage per tablet (250 mg per tablet). 500 mg / 250 mg per tablet = 2 tablets. Therefore, the correct answer is 2 tablets. Choices A, C, and D are incorrect as they do not accurately reflect the correct calculation based on the provided information.

3. What are the fine, down-like hairs on the newborn's ears, shoulders, lower back, and/or forehead known as?

• A. Vernix.
• B. Lanugo.
• C. Milia.
• D. Vibrissae.

Correct answer: B

Rationale: Lanugo is the term used to describe the fine, down-like hairs found on a newborn's ears, shoulders, lower back, and/or forehead. These hairs are different from vernix, which is a waxy or cheese-like white substance covering the skin of newborns. Milia are small, white, or yellowish cysts that commonly appear on a newborn's face, while vibrissae are the thick, stiff hairs commonly found around the nose and other parts of the face.

4. A client has a new diagnosis of chlamydia. Which of the following actions should the nurse take?

• A. Report the infection to the local health department
• B. Apply an antiviral cream to lesions
• C. Instruct the client to use condoms until the treatment is completed
• D. Initiate contact precautions

Correct answer: A

Rationale: The correct answer is to report the infection to the local health department. Chlamydia is a reportable disease, meaning healthcare providers are required to report cases to public health authorities for tracking and control measures. Choice B is incorrect because chlamydia is a bacterial infection, not a viral infection, so antiviral cream would not be effective. Choice C is important advice for preventing the spread of chlamydia but is not the priority in this scenario. Choice D is not necessary for chlamydia, as it is primarily transmitted through sexual contact.

5. Select the stage of shock that is accurately paired with its characteristic.

• A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
• B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
• C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
• D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.

Correct answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.
