Nursing Elites

1. The LPN is taking care of a 176-pound client who has recently been diagnosed with diabetes. The primary healthcare provider has written an order for Lantus� (insulin glargine injection) 100 units/mL, using weight-based dosing of 0.2 units/kg per day. The LPN should prepare ____ units for administration.

• A. 12
• B. 35
• C. 16
• D. 9

Correct answer: B

Rationale: To calculate the correct dosage, first convert the client's weight from pounds to kilograms. As 1 kg = 2.2 pounds, 176 pounds � 2.2 = 80 kg. The client should receive 0.2 units for every kilogram, which equals 16 units. Therefore, the total amount to prepare is 16 units x 100 units/mL = 1600 units. Considering the medication concentration of 100 units/mL, 1600 units � 100 units/mL = 16 mL. However, since the question asks for the number of units, the final answer is 16 units x 2 injections = 32 units. Therefore, the LPN should prepare 32 units for administration.

2. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?

• A. Use the defrost setting on microwave ovens to warm bottles.
• B. When refrigerating formula, discard partially used bottles after 24 hours.
• C. When using formula concentrate, mix one part concentrate and two parts water.
• D. If a portion of one bottle is left for the next feeding, discard it.

Correct answer: B

Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is crucial to be cautious when heating bottles in a microwave to prevent milk from becoming superheated. The defrost setting is recommended, and the formula's temperature should always be checked before feeding the baby. Choice B, which advises to discard partially used bottles of refrigerated formula after 24 hours, is also correct. This is important to prevent the introduction of pathogens by the baby into the formula. Choice C, recommending mixing one part formula concentrate with two parts water, is essential for ensuring the correct dilution. Choice D, suggesting to discard any remaining portion of a bottle for the next feeding, is incorrect. It is not necessary to discard the remaining portion if it has been refrigerated promptly and used within a safe time frame. Adding fresh formula to a partially used bottle is not recommended, as it can lead to the growth of pathogens that may be transferred to the new formula.

3. Which of the following foods should be avoided by clients who are prone to developing heartburn as a result of gastroesophageal reflux disease (GERD)?

• A. lettuce
• B. eggs
• C. chocolate
• D. butterscotch

Correct answer: C

Rationale: The correct answer is chocolate. Ingestion of chocolate can reduce lower esophageal sphincter (LES) pressure, leading to reflux and clinical symptoms of GERD. Lettuce, eggs, and butterscotch do not affect LES pressure and are less likely to trigger heartburn in individuals with GERD. Therefore, clients who are prone to developing heartburn due to GERD should avoid consuming chocolate to manage their symptoms effectively.

4. 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.

5. When teaching a woman about possible side effects of hormone replacement therapy, the nurse should include information about all of the following except:

• A. Hypoglycemia in diabetic women.
• B. The possible return of monthly menses when taking combination hormones.
• C. Increased risk of gallbladder disease.
• D. Increased risk of breast, cervical, and ovarian cancer with long-term use.

Correct answer: A

Rationale: The correct answer is 'Hypoglycemia in diabetic women.' When educating a woman about hormone replacement therapy, it is important to discuss the possible side effects. It is true that monthly menses might return when taking combination hormones, as the progestin can cause this. Additionally, there is an increased risk of gallbladder disease associated with hormone replacement therapy. Furthermore, long-term use of hormone replacement therapy is linked to an increased risk of breast, cervical, and ovarian cancer. However, hypoglycemia is not a common side effect of hormone replacement therapy, especially in diabetic women. In fact, estrogen can have a positive impact on glucose control in some cases, so hypoglycemia would not be a typical concern.
