A dispersion consists of a solute dispersed through a dispersing vehicle. Which of the following dispersions is a liquid for topical application that contains insoluble solids or liquids?
- A. Ointment
- B. Lotion
- C. Paste
- D. Gel
Correct Answer: B
Rationale: The correct answer is B, 'Lotion.' A lotion is a liquid dispersion that contains insoluble solids or liquids for topical application. Ointments are more semi-solid and occlusive, pastes are thicker and contain higher concentrations of solids, and gels have a jelly-like consistency due to their three-dimensional network structure. Therefore, among the options, a lotion is the most suitable choice for containing insoluble solids or liquids for topical application.

The client diagnosed with HIV is taught by the nurse that the condition is transmitted through
- A. the infection passed from a mother to her baby
- B. Tears
- C. human bites
- D. insect bites
Correct Answer: A
Rationale: HIV can be transmitted from a mother to her baby during childbirth or breastfeeding, making choice A the correct answer. Tears, human bites, and insect bites are not common modes of HIV transmission. While human bites can potentially transmit the virus, it is less common compared to mother-to-child transmission.
Before administering a scheduled dose of insulin to a 10-year-old child who is learning diabetic self-care, which information is most important for the PN to ask the child?
- A. How much exercise did the child have today?
- B. Did the child perform a finger stick?
- C. When did the child last urinate?
- D. Has the child eaten recently?
Correct Answer: B
Rationale: The correct answer is B: 'Did the child perform a finger stick?' Before administering insulin, it is crucial to check the child's blood glucose level to prevent hypoglycemia. Performing a finger stick blood glucose test provides essential information on the current blood sugar level. Choice A ('How much exercise did the child have today?') is not as critical as monitoring blood glucose levels directly. Choice C ('When did the child last urinate?') is not directly related to the immediate need for insulin administration. Choice D ('Has the child eaten recently?') is important but not as crucial as knowing the current blood glucose level.
After admission, which observation is most important for the nurse to report immediately for an adult client who weighs 150 pounds and has partial-thickness and full-thickness burns over 40% of the body from a house fire?
- A. Poor appetite and refusal to eat
- B. Systolic blood pressure at 102
- C. Painful moaning and crying
- D. Urinary output of 20 ml/hr
Correct Answer: D
Rationale: A urinary output of 20 ml/hr is a sign of inadequate kidney perfusion and could indicate hypovolemic shock, which requires immediate intervention. In this situation, with severe burns over a large portion of the body, monitoring urinary output is crucial to assess kidney function and fluid status. Poor appetite, systolic blood pressure at 102, and painful moaning and crying are important but do not indicate the immediate need for intervention like inadequate urinary output does.
While providing oral care for a client who is unconscious, the nurse positions the client laterally and uses a basin to collect secretions. Which intervention is best for the nurse to implement?
- A. Swab the oral cavity with a washcloth
- B. Use oral swabs with normal saline
- C. Provide a Yankauer tip for oral suction
- D. Support the head with a small pillow
Correct Answer: B
Rationale: Using oral swabs with normal saline is the best intervention in this scenario as it effectively cleans the oral cavity without causing irritation or dryness, which is crucial for an unconscious client. Swabbing the oral cavity with a washcloth may not provide thorough cleaning, and it can potentially cause irritation. Providing a Yankauer tip for oral suction is not necessary unless there are excessive secretions that need to be suctioned. Supporting the head with a small pillow, although important for comfort, is not directly related to oral care in an unconscious client.
The home health nurse suspects elder abuse after observing fresh lacerations on the arms and legs of an older adult male client who lives with his daughter. Which action is most important for the nurse to take?
- A. Document the lacerations in the client's record
- B. Report findings to the supervisor for referral to adult protective services
- C. Ask the daughter who has been taking care of the client on a daily basis
- D. Apply dry dressings after cleansing the wounds
Correct Answer: B
Rationale: In cases where elder abuse is suspected, the most critical action for the nurse to take is to report the findings to the supervisor for referral to adult protective services. This step is essential to protect the client from further harm and ensure their safety. Documenting the lacerations, as suggested in choice A, is important but not as urgent as ensuring immediate intervention by reporting the abuse. Asking the daughter for information, as in choice C, may not be effective if she is the abuser. Applying dressings, as in choice D, is a lower priority compared to taking action to address the suspected abuse.
