Hypernatremia is associated with a:
- A. Serum osmolality of 245mOsm/kg
- B. Urine specific gravity below 1.003
- C. Serum sodium of 150mEq/L
- D. Combination of all of the above
Correct Answer: D
Rationale: Step 1: Hypernatremia is defined by elevated serum sodium levels (>145mEq/L).
Step 2: Serum osmolality of 245mOsm/kg is high, consistent with hypernatremia.
Step 3: Urine specific gravity below 1.003 indicates dilute urine, a common finding in hypernatremia.
Step 4: The combination of elevated serum sodium, high serum osmolality, and low urine specific gravity confirms hypernatremia.
Summary:
A: Incorrect, as high serum osmolality (not 245mOsm/kg) is associated with hypernatremia.
B: Incorrect, as low urine specific gravity (not below 1.003) is seen in hypernatremia.
C: Incorrect, as serum sodium needs to be >145mEq/L to indicate hypernatremia.

A client with HIV has been prescribed anti viral medications. What instructions related to administration of medications should the nurse give such a client?
- A. Comply with the timing of antiviral medication around meals
- B. Avoid exposure to harsh sunlight for about 2hrs after taking the medication
- C. Have the medications with plenty of fruit juice
- D. Have an increased dose of the medications if the symptoms worsen
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. Timing: Antiviral medications should be taken as prescribed to maintain consistent drug levels in the body.
2. Around meals: Taking medications with or without food can affect absorption, so timing around meals helps with consistency.
3. Compliance: Following the timing instructions increases medication effectiveness and reduces the risk of drug resistance.
Other Choices:
B) Avoiding harsh sunlight: Not directly related to medication administration; may be a precaution for other reasons.
C) Having medications with fruit juice: This is not a standard instruction for antiviral medications; may not be suitable for all medications.
D) Increasing dose for worsening symptoms: This is dangerous and should only be done under healthcare provider supervision; self-adjusting medication doses can be harmful.
The nurse is teaching a client who suspects that she has a lump in her breast. The nurse instructs the client that a diagnosis of breast cancer is confirmed by:
- A. Breast self-examination
- B. Mammography
- C. Fine needle aspiration
- D. Chest x-ray
Correct Answer: C
Rationale: The correct answer is C: Fine needle aspiration. This procedure involves inserting a thin needle into the lump to extract cells for examination. It provides a definitive diagnosis of breast cancer by analyzing the cells for cancerous features. Breast self-examination (A) is a screening tool but cannot confirm a diagnosis. Mammography (B) is used for screening and detecting abnormalities but also requires further testing for diagnosis. Chest x-ray (D) is not used to diagnose breast cancer.
Which nursing diagnosis is most appropriate for a client with Addison’s disease?
- A. Risk for infection
- B. Urinary retention
- C. Excessive fluid volume
- D. Hypothermia
Correct Answer: C
Rationale: The correct answer is C, Excessive fluid volume. In Addison's disease, there is a deficiency of cortisol and aldosterone leading to sodium loss and water retention. This imbalance can result in excessive fluid volume. A) Risk for infection is not directly related to Addison's disease. B) Urinary retention is not a common symptom of Addison's disease. D) Hypothermia is not a typical manifestation of Addison's disease.
Wilma knew that the maximum time when suctioning James is
- A. 10 seconds
- B. 20 seconds
- C. 30 seconds
- D. 45 seconds SITUATION: A 45 year old male construction worker was admitted to a tertiary hospital for incessant vomiting. Assessment disclosed: weak rapid pulse, acute weight loss of .5kg, furrows in his tongue, slow flattening of the skin was noted when the nurse released her pinch. Temperature: 35.8 C , BUN Creatinine ratio : 10 : 1, He also complains for postural hypotension. There was no infection.
Correct Answer: C
Rationale: The correct answer is C (30 seconds) because the maximum recommended time for suctioning a patient is typically around 10-15 seconds for each pass. Prolonged suctioning can lead to tissue damage, hypoxia, and increased risk of infection. In this case, given the patient's symptoms and medical history (vomiting, weight loss, dehydration, hypotension), it is crucial to limit suction time to prevent further complications. Choices A, B, and D are incorrect as they exceed the safe duration for suctioning and increase the risk of harm to the patient. Choice D, in particular, is significantly longer than the recommended time and could pose serious risks to the patient's health in this situation.
What is a critical component of the evaluation phase in the nursing process?
- A. Determine if client outcomes have been achieved
- B. Revise the client’s health history
- C. Establish priorities for care
- D. Formulate new nursing diagnoses
Correct Answer: A
Rationale: Step 1: Evaluation phase assesses if client outcomes have been achieved.
Step 2: Determines effectiveness of nursing interventions.
Step 3: Validates if goals are met or adjustments are needed.
Step 4: Reflects on the success of the care plan.
Step 5: Choice A is correct as it directly relates to evaluating the effectiveness of nursing care.
Summary:
- Choice B is incorrect as revising health history is part of assessment.
- Choice C is incorrect as establishing priorities is part of the planning phase.
- Choice D is incorrect as formulating new nursing diagnoses is part of the diagnosis phase.
